Hello Pojo Fans,
Onto the priciest card we’ll be looking at this week: Seventh Tachyon.
A blunt opening for a card that was over a hundred bucks when first released, the price tag has cooled, but as of writing this, Seventh is still going to run you around $60 a piece. Despite that, it can allow pretty much any deck to have a dedicated piece of search weaponry for specific tech or in many cases, be an FTK/OTK enabler.
Restricted to revealing an Xyz with a number 101-107 in their name, this includes the chaos monsters as well. Once you make your choice, you get a Deck search of something that matches the same Type or Attribute, as well as match their Level to the Rank that was revealed. The FTK we’ll showcase on Friday is surprisingly easy to accomplish given Tachyon Primal being able to Special Summon itself when you have a Dragon Xyz on board, it searches Seventh Tachyon, and Schwarzschild Infinity Dragon can Special Summon itself when you have no monsters and become a one-card Rank 8 for Dragons…oh, and Seventh Tachyon being a Normal Spell can be searched by Triple Tactics Thrust. You get locked out of everything except Xyz Monster Special Summons from the Extra Deck once playing this, but by that point you are likely a hop, skip, and a jump away from winning.
FTK/OTK not your thing? Good. This card is still a menace. Fourteen different monsters you could reveal out of the Extra Deck to search something. Able to cover five different Attributes, four different Levels, and six different Types out of the Extra Deck, there’s so much you can search and literally any deck could play this card. Aside from the FTK/OTK mentioned, Ryzeal can get another search, everyone can get an Artifact Scythe or Mulcharmy Purulia, or Blue-Eyes can opt to get another search as well. Altergeist even can use this as another search option.
It is worth the price tag, sadly. By playing it, at least one card to get to it, and one spot in the Extra Deck for your targeted reveal to align with the search, you have a great search card. It doesn’t need your opponent like Talents or Thrust, and while it does take up room and even need something like Primal to search it, you can always play a set of it and hope to hard draw or fish it out through deck thin/draw cards. While all decks could play it, the real question is if you can afford it, or if you’d have to curb your strategy to play a set without losing consistency.
Advanced- 4.5/5

Now for the most hyped card of the set for many Xyz Decks and Decks that don’t need to use the Extra Deck, but have search targets for this card: Seventh Tachyon.
Seventh Tachyon is a Normal Spell that lets you reveal a Number Xyz from your Extra Deck with a number between 101 and 107 in its name to let you add a monster from your Deck to your hand with the same Level as that monster’s Rank and a matching Type or Attribute as that monster, then you place a card from your hand on top of your Deck (Rank-Up-Magic – The Seventh One is intended) and then you cannot Special Summon from your Extra Deck for the rest of the turn that aren’t Xyz Monsters. The Extra Deck lock is fine considering Decks using this are either focused on Xyz Summoning or not summoning from the Extra Deck at all. With this card existing now, you can search for any Level 4 monster with the WATER, FIRE, EARTH, or LIGHT Attribute or the Aqua, Fairy, Spellcaster, Warrior, or Rock type. You can also get any Level 5 monster that is WATER, LIGHT, DARK, FIRE, or EARTH Attribute or Aqua, Fairy, Spellcaster, Warrior, or Rock. Finally, since Number 107 has to be completely different, any Level 8 or 9 monster that’s LIGHT and/or Dragon is searchable. It’s a wide search range that completely leaves out WIND monsters without the corresponding Types, but there’s a ton of uses for this card. Sharks would love this to reveal Number 101 or 103 and their Number C forms to search Buzzsaw Shark, Surfacing Big Jaws, or Lantern Shark. Ryzeal uses this to reveal Number 102/104 or Number 105 to search for their LIGHT and FIRE Ryzeal Monsters respectively, plus Number C102 or Number C103 gets Artifact Lancea to stop Maliss. K9 will likely use Number C101, Number C102, or Number C106 to search for some of their main play enablers as well. There’s a wide array of options this allows for if you only need to Xyz Summon if you use the Extra Deck. It was limited in the OCG to slow the consistency of Ryzeal and other Decks that could use it, while the TCG just got it and don’t always use it if they run Fiendsmith Ryzeal, which is mostly possible over here due to Engraver being at 3. HOPT on this card, of course. It’s a great card in many Decks that could use it since there’s a wide array of monsters it can search, making up for the fact it is technically a minus to activate. You’ll even see this ran with Seventh Ascension just to search for this to have up to 6 copies in your Deck. If you can accomidate for a card like this, then it’s a near surefire card to run.

One of the most highly anticipated and controversial cards this year, it’s none other than the Normal Spell, Seventh Tachyon. While Tachyon proper can search it just fine thanks to Divine Golden Shadow Dragon Dragluxion, you’ll usually want to hard open this card– which is helped by Seventh Ascension, which directly searches it! Seventh Tachyon can only be activated once per turn and has a single effect, revealing a Number Xyz monster in your Extra Deck between 101 and 107 to search any monster from your deck with the type or attribute and a level equivalent to its Rank, with the drawback of making you place a card from your hand on top of your deck and locking you into Xyz monsters from the Extra Deck for the rest of the turn. The placing part is meant to enable cards like Rank-Up-Magic – The Seventh One, but since that strategy kinda sucks, you’ll usually just want to put away an excess card or, ideally, a garnet or brick like Mathmech Nabla in Mathmech Ryzeal hybrids. As for the effect itself, it’s no surprise that many players sounded the alarm, because yes, there are a lot of cards you can search with Seventh Tachyon. In addition to Schwarzschild Infinite Dragon itself, you can grab Exosister Martha, Mathmech Circular, Sakitama, Vanquish Soul Razen, various Barrier Statues, and, of course, Ice Ryzeal and Ext Ryzeal. Many decks can use Seventh Tachyon, but the strongest so far has been Ryzeal, causing it to be Limited in the OCG in conjunction with the infamous Tachyon FTK, which involved searching (the now banned) Catapult Turtle. The Xyz lock might seem pointless, and it is for many decks, but ironically it’s been causing some rifts in the Ryzeal community, as playing it means you lose out on deck space for the Fiendsmith engine. As much as I love this card as a consistency booster for a lot of decks, it does have an absurd range of search targets, so I would understand if it inevitably got hit here too. You’ll tweak the ratios to taste depending on how much consistency you need– after all, it’s basically 6 more copies of a combo starter for quite a lot of decks if you run all 3 copies and Seventh Ascension.
+Massive pool of generic monsters it can search, particularly combo starters for many decks
+Can help put garnets and bricks back in the deck
-Locks you into Xyz monsters
-Placing a card back can be annoying
Advanced: 4.5/5
Art: 3/5 Mizar on the weekends.
