This is one of the most difficult Axie Infinity endgame tanks I've ever learned to use, but it is strong as hell. Behold, "Egg Fish!"
Looking at the moveset closely may only confuse you further...
I didn't realize it before now but it turns out that Eggbomb is a playable move on a fish if it has the Koi tail and other aqua cards. Since this Axie can speed itself up, there is a lot of potential to go first on multiple turns in a match and use the egg to control the flow of play.
With the huge shield stat on the Shipwreck card combined with eggbomb's Aroma effect, there is a lot of outplay potential.
It's not easy though because you need a good read on your opponent to make the correct decisions when playing with an Axie like this. It also requires good awareness of your matchups and how to outplay other teams.
