Those are my votes, those cards were chosen also because they make sense, and do not have an overly complicated way to work:
-Nimbus: air-water incoming!
-Dodge: Air doesn't have any buff card, so at least it could have an alternative to quintessence with this card.
-Prevailing Winds: an alternative way to use the easily-produced air quanta, and it makes Thunderstorm stronger. Definitely needs higher cost though (what if you draw it late in the game?)
-Kamikaze: Finally a weapon you can stack in your deck. Synergy with Animate Weapon: make a weapon deck, and when playing, replace Kamikazes with whatever weapon you draw next (including other Kamikazes), but when you wanna replace other weapons, animate them.
