Wormhole will be broken with Pharaoh and FFQ.
Yes, it will be powerful with creature spam. But bear in mind that you can only carry around 6 of them. Also bear in mind that it costs Aether quanta; Aether itself has no creaturespam.
The ability to put crap on opponent's topdeck is, eh, OP.
It's powerful, I agree. But all you need to do is discard it. This card is really great at slowing down the opponent, but, really, it's only a 1 turn thing.
Warp Hole is the only unconditional kill in the game, again, not exactly right.
Are you acquainted with Shockwave? How about Antimatter? Otyugh, perhaps?
See my 2nd post on this thread.
Again, I created these cards with one purpose in mind - a set of powerful Aether cards that can help the element have some synergy with other elements. As it stands, Aether is sort of a loner. Mono-Aether rocks, but it doesn't have that many synergies with other elements - Time and maybe Death come to mind, but nothing else. These cards may help establish some connections for one of the loneliest of elements.
If you still think they're overpowered, I may consider increasing the costs to 4
unupped and 7
upped. I will wait for more reception before making such a decision.
