Two Fronts

Create a battlefield, then each player may move
any number of permanents they control onto
that battlefield. Exile Two Fronts. (Permanents
on a battlefield can only refer to a battlefield they
are on. Whenever a player casts a permanent spell
or plays a land, that player decides which battlefield it enters. Creatures can only block creatures on the same battlefield and attack planeswalkers on the same battlefield. Players can only pay mana to cast
permanent spells onto a battlefield produce
