The "legend rule" doesn't 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 token copy that attacks that opponent this turn if able. They gain haste. Sacrifice them at the beginning of the next end step. Activate only as a sorcery.)
