Forgetful Fish list. 1v1 constructed format - don't draft this.

• The library and graveyard are shared by both players. Cards are "owned" by the player who played them.
• You can reveal and freely mulligan starting hands with 0-1 lands or 6-7 lands.
• If the order of both players drawing ever matters, have the active player deal like it's poker (NAP, AP, repeat).

Play revolves around topdeck control and permission.
Because the library is shared, a Memory Lapse cast on an opponent's turn will draw you whatever spell was countered. That is, unless they draw it themselves first.
The only source of damage is Dandân. Damage is always dealt in increments of 4.
