This card is hard to deal with, as it requires damage to already be on it before it can be knocked out, making it a two-turn task for many decks
On the other hand, if you're having a hard time choosing between a couple of the decks, hopefully this ranking will at least give you something to think about and might even be a good tie-breaker if you can't make up your mind
Pay the Shinedust and exchange it for Special Shop Ticket
Note that older versions of cards that have received an errata are tournament playable even if they do not have the corrected text printed on them
"X-Head Cannong" + "Y-Dragon Head" + "Z-Metal Tank" This card cannot be Special Summoned except by removing from play the above cards on your side of the field, then you can Special Summon this card from your Fusion Deck (You do not use "Polymerization")
