I totally can't see this being OP at all! Doubling your quanta production from the first/second turn isn't a huge advantage at all!
Imagine makin a deck wich contains
6 elite phase dragons
6 supernarual condivisions
6 aether towers
6aether pendulumns (yes we care about earthquake even in examples
)
6 elite immortals
imagine a lucky hand loosing the coin-flip and getting 4AT 3AP and 1SC, great now you have 25 aether quanta on turn 1 and then...aether doesn't have draw power speed to be that effective, sure pretending you keep being lucky hand topdecking only dragons you can play 1 dragon at turn(from turn 3), is that OP, not but prolly with SoBra will make a good combo.
Imagine a deck wich contains
6 Phase recluses
6 twin universes
6 supernatural condivisions
6+6 towers-pendulumns
Lucky hand:
(coinflip loss) 4AT 3AP 1SC>11aether quanta but then again what you're gonna do on turn 2 with25+1 quanta without draw power? let's suppose we insert SoBra instead of PU, we topdeck SoBra and then keep drawing 1SoBra and 1 recluses with the last draw being 2 recluses(and the oppo having its hand empty since turn 2, sure a very good combination, but pretty unlikely.
I say that it cost enought to don't advantage too much its element(wich has expensive creatures) and have an high prize to be putted in rainbows being effectiveand efficace and might compromising the drawing (at least 4/5 copies).
Imagining Furballdn going into lost archieves just to let me see that has been done before in 1942 by christopher columbus : (I MADE BAAAAAAAAAAAAAD MATH 'CAUSE I'M HELLA TIRED, APOLOGIZES FOR THE MEGA EDITING.
I stil think it's not that OP.
