If the description doesn't deceive me, you can also use this against your opponent.
Perhaps it may sound absurd, but as mentioned, this card has limited uses outside of a few specific low cost cards. The high cost of the card itself limits much of its usefulness. I get a feeling this will be drafted aside once implemented, unless it is for niche situations, like Nymph Tears.
Being part of the Aether set, it is tricky because the nature of the card *DOES NOT* let "Fractal" an Aether creature and then play it 5-6 times. As for Rainbows/Duo decks, it will have more usage, but the expensive cost of it coupled with the expensive cost of a multitude of the better cards will make Fractal a card used in limited amounts.
The only situation I can easily think of are Light/Aether decks capitalising on Hope, or Aether/Fire, but with Phoenix/Ash, I think Mono-Fire would be stronger than Aether/Fire. I cannot really think of an elemental duo combination that Fractal would be useful for, since it is difficult to gather enough Quanta to play Fractal in the first few turns of a game on average.
I can imagine Fractal being used:
- Bringing one creature card and fractal it, then spamming it. Works great in speed life decks, but not so much other speed decks. Doesn't avoid the problem of running a duo deck, and adding +5 creatures would beat adding 5++ cards to set up an effective duo.
