I'm aware. The Legendary Fisherman's effect itself is centered around Umi, and water support is generally better than wind support.

Regarding Fire Fists, I don't like just picking archetypes. To me, just picking up random archetypes you're unfamiliar with is like making a cookie cutter deck. Even if I get to learning the card effects and how they work together, the actual flavor doesn't really appeal to me.

I've been PMing KOgaming, and we've been discussing things to that effect. (Gameplay thematicism vs. Monster and flavor thematicism)

I've bought up a lot of decks that mainly focus on the first; manners of elegantly getting off certain gameplay goals and cards that help make that happen. Instead of saying "this character is whimsical, you can tell by how they use the monster Baobaboon." I can say "this character is whimsical, you can tell by how they seem to do something dumb or suicidal every turn only to reveal it's to their benefit."

Granted, this comes at the expense of the thematicism of their cards overall, which is a valid point, but saying I'm not going to find a gameplay style to match their personality but I'll find an archetype that stylistically matches them seems disingenuous, but that's just my opinion.
