Dominarian Apocalypses. They happen all the time.
Now relive the aftermath of everyone's favourite world-ending cataclysms from everyone's favourite world with this 2-4 player sudden-death microcube~!

Build 15 card decks that really make you -feel- like you're struggling to survive in a post-apocalyptic wasteland.
Improvise whatever you can from the relics and ruins you can scrounge up!
Recruit veterans of a lost war, forgotten war machines, living nightmares, or the lucky few who were so pathetic as to be totally beneath notice!
Despair as others take what you so sorely need!
Desperately try to generate enough coloured mana to cast your spells!
Cry as you futilely waste resources trying to hold on to your last scrap of hope!

Grid draft, 15 card decks, 1 life, no lands beyond what you draft. Yes that means no basics. Be the last to die.
Games should last as long as you would during a real apocalypse - about 2 minutes.

2p - Standard grid draft, 8 packs of 9.

3p - Modified grid draft, 6 packs of 9. 1st pick gets a row or column, 2nd pick gets a remaining row or column, last pick gets all the dregs. Really harsh.
Players A, B and C:
Pack 1: A, B, C.
Pack 2: B, C, A.
Pack 3: C, A, B.
Pack 4: C, B, A,
Pack 5: B, A, C.
Pack 6: A, C, B.

4p - Modified grid draft, entire cube. Whenever a row or column is taken, replace it immediately. Players A, B, C, and D. Pick order is just A, B, C, D.

Thinking about adding Field of Ruin over Radiant Fountain but I want to have as many outs to Tormented Hero as I can.
Looking for room for Spatial Contortion, very hard to make a cut.
