A new set means a new countdown of the best cards in said set, so we're bringing you the Top 10 Cards (as voted and polled by us) from Lord of the Tachyon Galaxy! We open at #10 with Legendary Atlantean Tridon. This card has a LOT going for it. A Level 3, Water attributed, Sea Serpent (like Atlanteans aren't going to make sweet love to this card all ready) with a respectable 1600 attack and 800 defense.

What does he do...hell, what doesn't he do would be more accurate. He speeds up in Special Summoning of the heavy hitter for the Deck, Poseidra, by tributing himself and another Sea Serpent Monster. He has an attack reduction effect to all your opponent's Monsters of 300, if successful, and Poseidra can lower attack too. I mean, he's fast, his attack is decent, and he combos with the boss. You play two, if not three of this, I'd say probably one per Poseidra.

Ratings: (in its Deck)

Traditional: 3.5/5 This Deck actually is legit here
Advanced: 4.5/5
Art: 4/5

The card we are going to review today gives us a different twist to the Atlantean/Mermail decks currently being played. The top tier Mermail decks rely on level 7 monsters for their effects and to make rank 7 Xyz monsters. Legendary Atlantean Tridon is a perfect fit for a Mermail deck. It is a level 3 Sea Serpent so it can be easily special summoned with Deep Sea Diva or Atlantean Marksman and then use its effect to special summon Poseidra the Atlantean Dragon, a level 7 monster. It can also be searched from the deck with Mermail Abysspike.

If you are playing Legendary Atlantean Tridon, then you are obviously playing Poseidra as well. Sense Mermail decks are playing Abyss-squall, getting Poseidra to the field if it is in you hand or grave is made even easier. With 2800 in attack, Poseidra makes for a pretty formable foe.

Legendary Atlantean Tridon does some pretty cool things besides summoning Poseidra. When Tridon special summons Poseidra, the last thing that happens is the attack loss, so cards that respond to the summon, like Bottomless Trap Hole, will miss their timing. The second cool thing is that Tridon will trigger the effect of the monster it tributes, so if you attack with Atlantean Marksman and use its effect to special summon Tridon, during main phase two you can tribute the Marksman to special summon Poseidra and still get marksman’s effect.

Legendary Atlantean Tridon could change the way Mermail decks are run if they prove to be consistent. You only need one Poseidra so getting stuck with dead cards is less likely and there are a ton of ways to special summon Poseidra even if it is in your hand. You can even use it as one of your discards for your other Water monsters. Mermail decks run pretty good as they are built now, so Tridon could have a tough time making its way into an already packed deck could be a tough task. The nice thing about Tridon is all you need is one Tridon and one Poseidra to make it playable in a Mermail deck.

Traditional: 2/5
Advanced: 3/5


It's time for the top ten cards of Lord of the Tachyon Galaxy, and at #10 is Legendary Atlantean Tridon. I'll be honest, I really overlooked this card. Since it's a Atlantean monster, it goes along with all the good stuff that comes along with it. Stats aside, it makes Poseidra, The Atlantean Dragon a bit more playable, as you can tribute this card and another Sea-Serpent monster you control to special summon Poseidra from your hand or deck. That's pretty good because you get the effect of the other Atlantean monster you used to tribute for Poseidra. Tridon's other effect of all of your opponent's monsters they currently control lose 300 ATK isn't that bad, but isin't all that important. Tridon is a great card and adds to the powerhouse Atlantean deck. Now only if it said, "Special summon from Hand, Deck OR graveyard" it might have gotten a higher place on our list.

Traditional: 2.5
Advanced: 4


We start off our top ten countdown this week with: Legendary Atlantean Tridon

"You can Tribute this card and 1 Sea Serpent-Type monster; Special Summon 1 "Poseidra, the Atlantean Dragon" from your hand or Deck, then all monsters your opponent currently controls lose 300 ATK. "

This card is pretty straight forward. You have to run sea serpents (that's not bad), and either straight Atlanteans or Poseidra Frogs (ehhhhh....yeah no. ). I could see him being in some really fun decks for low level play, but since he includes neither Spellbook or Elemental Dragon in his name we probably won't see him much at the next YCS. (prove me wrong, PLEASE.)

Advanced: 2/5

Traditional: 1/5


For the next 2 weeks, we will begin with the team's Top 10 list of the best cards within the newest set: Lord of the Tachyon Galaxy.

To start off from the bottom of the list, a sleeper common that will certainly boost a previously-released Structure Deck: Legendary Atlantean Tridon.

This Sea-Serpent has a solid 1600 ATK and 800 DEF. Its effect is actually pretty good. Take a look.

"You can Tribute this card and 1 Sea Serpent-Type monster; Special Summon 1 "Poseidra, the Atlantean Dragon" from your hand or Deck, then all monsters your opponent currently controls lose 300 ATK."

Needless to say, a lot of people has came to the conclusion that Poseidra is simply too difficult to consistently bring it into play. Now with Tridon around, it's a lot easier to pull off.

First of all, this works very nicely with Deep Sea Diva, our resident Sea Serpent searcher. Deep Sea Diva will call out Tridon straight from your deck and since Deep Sea Diva is a Sea Serpent herself, she will meet the requirements for Tridon's effect, giving you a Poseidra on the field for just one card. This makes Deep Sea Diva even better now. Instead of making just Rank 2 Xyz, Level 5 Synchros but now Deep Sea Diva is your one-card way to calling out a 2800 ATK monster on the field.

That's pretty neat.

Secondly, it works nicely when you have an Atlantean on the field since Tridon's effect will trigger your Tributed Atlantean's effects.

Atlantean Dragoons? You get a Sea Serpent search along with a Poseidra on the field.
Atlantean Marksman? Get rid of a Set card along with a Posidra summon.
Atlantean Heavy Infanty? I'm sure you get the idea.

The second part of Tridon's effect is small and almost pointless but it does come with an interesting benefit. Since that part happens AFTER Poseidra is summoned, this can and will miss the timing on Torrential Tribute, Bottomless Trap Hole, and other similar cards since the last thing that is happening once you use Tridon's effect is the ATK reduction, not Poseidra's summoning. That's pretty cool, keeping your freshly-summoned boss monster around to have some fun. This effect also makes it easier to crush bigger monsters that Poseidra can't deal with in battle by itself. There isn't many that would qualify in this case but it can come in handy. After all, a Blue-Eyes White Dragon can actually block your way to victory and Tridon's effect can be all you need to crush it in battle.

All-in-all, this is what a common in a core set should be: overall useful, flexible, and can add more routes for previously-existing strategies. If you ever wanted to finally put your Atlantean boss monster to use, start looking for this card.

Traditional Format: 1/5 (It won't make the cut there. There is far better cards.)
Advanced Format: 3/5 (It's pretty good here. If Poseidra ever sees competitive play, I'm sure Tridon will be a big reason why that has happened.)


Legendary Atlantean Tridon
WATER/Sea Serpent/Effect/LV3/1600/800
You can Tribute this card and 1 Sea Serpent-Type monster; Special Summon 1 "Poseidra, the Atlantean Dragon" from your hand or Deck, then all monsters your opponent currently controls lose 300 ATK.

This week, we being looking at the top 10 cards from Lord of the Tachyon Dragon, as voted by us Card of the Day reviewers. At number 10 is Legendary Atlantean Tridon a new Atlantean, in fact the only new Atlantean in this set. Anyways before I get into another archetype support rant, let’s have a look at the card.

Legendary Atlantean Tridon has an interesting effect, by tributing this and another Sea Serpent you can special summon Poseidra from your hand or deck, then all monsters your opponent has lose 300 ATK. Well summoning a monster, especially 1 with 2800 ATK from your deck is a powerful effect and the fact that you get a mini version of Poseidra’s own effect does help. The main problem I have with this card is the fact it doesn’t have an “cost” effect like most other Atlanteans have.

Overall, if you play Atlanteans this guy should be seeing play in your deck.

Tradtional: 3.5/5
Advanced: 3.5/5


Welcome to our top 10 countdown for Tachyon Galaxy! I will admit.... There are tons of amazing cards in this set and it was very hard to make a top 10 list for this set. At the end of this, if you would like my top 10 list, please feel free to PM me on Pojo, and I will be glad to send you my list.

Today we are looking at a card that I am enjoying quite a lot right now, lets take a look at Legendary Dragon Tridon!

Legendary Atlantean Tridon
WATER/ Sea-Serpent/ Level 3

You can Tribute this card and 1Sea Serpent-Type monster;Special Summon 1 "Poseidra, the Atlantean Dragon" from yourhand or Deck, then all monsters your opponent currently controls lose 300 ATK.

1600 ATK / 800 DEF

This card has a ton of potential for pure Atlantean decks, or as I like to call it "budget mermail". In combination of other Atlanteans, you can easily abuse their boss monster. This and Deep Sea Diva is a one card Poseidra and this with Heavy Infantry is a two card Poseidra that destroys one face-up your opponent controls. In addition, it's a level 3 and thus can be summoned off of Marksman, thus summoning a rank 3 or Poseidra that pops a set card your opponent controls.

As you can see, this card fits perfectly with all their support! It also sets up Call of the Atlantean plays, and thus even more spam can be made.

Sadly, the biggest disadvantage of this card is that it requires other cards to be useful. Without another sea-serpent, it's quite useless. Also, this card can summon Poseidra from hand, you never want to see Poseidra there. Furthermore, Posiedra is rather a mediocre card, as it will just be a 2800 attacker for the most part. Luckily, it does allow you to get easily access into the Mermail rank 7 thanks to another new card from this set, Tidal.

Advanced: 3.25

There is a lot of potential for a Pure-Atlantean deck thanks to this card. If Mermails get hit, this can create a viable deck.

Traditional: 1.5

Water decks seem meh here... I wouldn't advise it here

Art: 3.0

It's a baby Posiedra. It's kinda cute!
