The things I am trying to accomplish with this cube are:

• Push against the 2-for-1, cardboard theory of modern MTG
• Encourage small games while ensuring they are fast and dynamic
• Have most of the gameplay happen during the combat step
• Make bluff attacks real. Are they holding up a combat trick, have a ninjutsu card, or just want to trigger raid? Or is the card in their hand a basic land?
• See interesting combat interaction battles on the stack

• No way to gain card advantage (real or virtual) without attacking. Defined as cards in hand, cards playable from exile, or permanents on the battlefield. This means:
  • No clean 2-for-1s
  • No non-cantrip card draw
  • No cards that generate multiple permanents, except by attacking
• No way to win except by attacking. This means:
  • No face burn
  • No mill
  • No alternate win conditions/infinite combos
• No DFCs

• Generate tokens on attack, build up with +1/+1 counters, play combat tricks
• Generate value by getting evasive creatures through, use countermagic to play a tempo plan, cheat out 5/5s by filling the graveyard with spells
• Punish opponents with bad blocks, trade low value creatures for high value, get value from raid
• Create swarms of goblins, trigger non-combat damage with Cavalcade of Calamity effects, trigger prowess
• Be the biggest thing on the board, curve out, go tall with +1/+1 counters
