Super Vegito

The "legend" rule does not apply to slivers you
control.
Each sliver creature card in your graveyard has
encore {x}, where X is its mana value.
Encore {5} ({5}, exile this card from your graveyard:
for each opponent, create a copy token that attacks
that player this turn if able. They gain haste.
Sacrifice then at the beginning of the next end step. Activate only as a sorcery.)
