pretty sure you could get away with making this a lot cheaper/ more powerful. Alone the upkeep of two different types of quanta and 1 health per turn are barely worth 2 or 3 attack. Alternatively you could have it affect ALL airborne creatures.
Ya... I was thinking of having it affect all airborne creatures... but I have a feeling there would be an awful lot of people screaming OP if I did... Partly because it ends up becoming a mass CC on a stick. With 3 in play at once, you effectively have a RoF every turn. Then just snipe or shockwave the stragglers. Wings keeps any ground dwellers that aren't affected at bay.
Alternately, the combo with wyrms / pegasi and blitz gets VERY upgly. Upgraded, they can handle 3 hits from this, yielding +9 ATK each. Then throw in dive and blitz on top. That gives +36 each. Very quickly adds up to an OTK.
I can drop the
upkeep or cost... or both... if it seems like too much though.
