Collateral

Whenever a creature you control deals combat damage to a player this turn, each player sacrifices a land and creates a colourless rubble artefact token with Accumulate (Whenever you would create a token of the same name as this one, instead place a {e} on this token. If the ability of a spell or an activated ability would destroy or require you to or sacrifice an artifact, you may remove a {e} from this artifact instead.)
