Into play is enough. Looking into making the Eldrazi a possibility before hitting 10ish mana, but I still want them to hit the board later in the game. In fact, into play is probably better than casting them. They should lose something if they're cheated, ya know?Do you need the cast trigger like Shelldock isle? Or just getting it in play is enough?
Ignite the Future is pretty sweet because it has an earlier game use and that's a totally fair effect for 8. I really like cards that enable something early and late.
Piper and Champion of Rhonas are a little too early, but they have to survive a turn and they're pretty fragile and they probably create a ton of tension.
WotC really put a lot of words on Ilharg. 6/6 trample for 5 isn't enough... Hmm... Maybe if it also came with an Emrakul? It might be alright if Piper and Champion are, but goddamn WotC.
Breach feels like it's 5 mana annihilator 4 and then the cube's namesake dies, so that's not quite what I'm after here, but the art is awesome.
