Again, 9+ , 14 and 4 cards for 3-10 dragons? Not to mention you can only have dragons on your field when you play the sparks. As for Fractal Spark + this + Giant Frog, I'd rather just Fractal Giant Frogs.
Well, in unupped you'd probably not want to strain your Life Quanta too hard, so you'd probably only have a few dragons and work more with cocks and frogs. Cock dies, turns into a frog, frog dies, turns into a cock. Here there's no reason to fractal the frogs and very little reason to fractal the cocks. (You probably won't have the quanta to get the smaller amount of damage increase.)
In upped play it gets a whole lot worse, because the same concept leaves them doing more damage for the same cost and it becomes a lot easier to gain quanta. And in upped play you never want to fractal a frog over a Ball Lightning, because once your first Ball Lightning dies the rest become 7/2 creatures. You don't even need Frogs.
Turn 1: 3 Aether Towers, 2 Aether Pendulums, Fractal, Evolution. Play towers and gain 5
Quanta and 1
quanta.
Turn 2: Draw Ball Lightning. Receive Quanta. You are now at 8
4
Turn 3: Draw Aether Tower or Pend. You are now at 9 quanta. Play Ball Lightning and Fractal 8 more. Those other 8 become 7/2 after the first one dies. So a total of 5x1 (5) + 7x8 (56) damage, for a total of
Turn 4: Attack with your 8 7/2 creatures for another 56 damage. Essentially all CC is helpless here, and win.
Granted, this is a bit of an extreme example. Not sure if this is a problem, or what to do if it is.
