Hello Pojo Fans,

Superancient Deepsea King Coelacanth FINALLY has gotten some support of sorts with the Ghoti archetype and is our Throwback Thursday choice.

Level 7 2800ATK/2200DEF, SDKC got lost in the shuffle of Phantom Darkness and with it being a Level 7 it was one star off from at least having Trade-In to help it be something. Its time wasn’t able to happen back then because there wasn’t many good Fish monsters to help it excel. It had a fantastic effect on paper, just…it’s only Fish-Type monsters, and back then (2008), there weren’t many. With a single discard you got as many Level 4 or lower Fish-Type monsters from the Deck to the field as possible. Back then, that meant several 7 Colored Fish, Ryal Swap Eel, and Great White. It was really just a big monster that could get you a bunch of monsters to use for Tribute Summons or Synchro and Fusion Summons. The Fish effects are negated, but until now that hasn’t meant anything. Now though, you’ve got much more Fish in the sea to choose from, as well as ways to search out SDKC and Special Summon it.

Tribute a Fish other than itself and you have a targeting negation and destruction effect. With SDKC’s Special Summon ability, you could have up to four Fish-Type monsters to fuel this, but now, with Xyz, Link, and more choices in the form of Synchro Monsters, you’re likely using SDKC for a BIG turn. The negation ability is good, but a one discard Link 4 is tough to pass up, let alone all the Synchro Summoning that can happen.

The Ghoti archetype need Fish-Type monsters to banish for their effects, and SDKC can make that happen, as well as get to the smaller Ghoti monsters to trigger their effects while banished. Within the archetype, Superancient Deepsea King Coelacanth is a The Most Distant, Deepest Depths times four.

Throwback Thursday this week brings us back to one of the earliest pieces of generic Fish support that helped the Type see some meta relevance back in the Synchro era: Superancient Deepsea King Coelacanth.

Coelacanth is a Level 7 WATER Fish with 2800 ATK and 2200 DEF. Great stats on a Level 7, plus we’re still running with WATER/Fish. First effect is a soft once per turn, letting you discard a card to summon as many Level 4 or lower Fish monsters from your Deck as possible with their effects negated and unable to attack. This is a pretty strong swarming ability to help make Extra Deck monsters. It was better when Fishborg Blaster was legal since that’s a Fish Tuner that can keep coming back as long as you had the discard fodder and a Fish on board, plus Oyster Meister was great to summon Tokens when it was used as Synchro Material. The Synchro spam isn’t as strong with this since Fishborg Blaster has been banned for over a decade, but summoning this does get you some nice Synchro or maybe Link spam. Second effect works during either player’s turn when this thing is targeted by a card effect, letting you tribute another Fish monster to negate the effect and destroy that card. I mean, targeting protection is nice, but honestly if you’re running this, it’s likely going to be used as Synchro Material since Level 7 is pretty good with low Level Tuners. It’s a pretty good piece of Fish support that aged well since its release in Phantom Darkness as we got more good Fishes. Whether you run Ghoti or not, it’s worth figuring ouut something with this guy to field spam.

Looks like we did this once almost 15 years ago, and most of us at the time weren’t too fond of this card.  But Throwback Thursday goes to (takes breath) Superancient Deepsea King Coelacanth.  Level 7, Water/Fish, good stats at 2800/2200 to start.  Once per Turn, a discard of any card allows you to Special Summon as many Level 4 or lower Fish Monsters from your Deck.  Said Monsters have their Effects negated and can’t attack.  So you swarm with this guy, build up into other Monsters, or use those Monsters for other things (in the case of the Ghoti, you’re likely removing the hell out of them to activate other Effects and combos).  The protection Effect here IS nice enough, where if it’s Targeted while face-up, you can Tribute another Fish you control to negate the activation AND destroy the card in question, if successful.  While this card itself isn’t huge on the removal, it’s still a nice set-up and combo card for the Ghoti, and the 2800 atk isn’t anything to sneeze at either.  In the Theme, I’d certainly welcome one or even two.

Art:  5/5  Creepy, very creepy indeed, but it does work with the name.  Looks rather fossilized or something, at least.

Say that three times fast; this week’s Throwback Thursday is Superancient Deepsea King Coelacanth, which invariably comes up whenever Fish monsters are mentioned. One of the game’s “buzzcards”, Coelacanth is a level 7 WATER Fish monster, making it searchable by Ice Barrier and most Fish support. Though we’re used to level 7s usually having awkwardly low stat spreads compared to level 8s, Coelacanth does have a respectable spread of 2800 attack and 2200 defense, so it’s not bad for combat in a pickle. 

While Coelacanth has traditionally seen play in powerful Fish Synchro decks, the ban of Fishborg Blaster has rendered it much like Snake Rain and Rekindling– that is, “ticking time bombs waiting to be broken”. Coelacanth is most known for its first effect, which is a soft once per turn; by discarding one card, you can Special Summon as many level 4 or lower Fish monsters as you wish from your deck, at the cost of negating their effects and preventing them from attacking. In the past, you would always pick Fishborg Blaster and Oyster Meister and perform insane combos with T.G. Hyper Librarian, Shooting Quasar Dragon, and Trishula, Dragon of the Ice Barrier. Nowadays, Oyster Meister is still an excellent target, though you’re limited to the less-powerful Gluttonous Reptolphin Greethys and the Ghoti Tuners. Mind you, you can still make insanely powerful boards, but with the advent of hand traps, plus the elephant in the room of actually summoning Coelacanth, Fish Synchro turbo is largely limited to casual play. The easiest way to summon Coelacanth is with anything that summon it from the hand, like Icejade Tremora or Paces, Light of the Ghoti, but you can also use Lifeless Leaffish and a level 4 extender to summon it with Number 60: Dugares the Timeless. Coelacanth’s lesser-known second effect is oddly a non-once per turn Quick effect, letting you tribute another Fish monster you control to negate an effect that targets Coelacanth and destroys the card. It’s a funny way to protect yourself against Effect Veiler or Infinite Impermanence, but if you’re leaving Coelacanth on the field instead of performing a combo, something has gone horribly wrong. Overall, still an incredibly powerful card in a vacuum, but it doesn’t quite have a meta home at the moment.

Advanced: 3.75/5

Art: 4/5 Cool and scary, now that’s the Halloween spirit.
