Malevolent Supremacy

During your turn, if an ability causes you to sacrifice one or more nonland permanents, you may sacrifice any number of nonland permanents controlled by opponents in addition to your own. When you do, return those permanents to the battlefield under their owner’s control at the beginning of the next end step with a safety counter on them. (Safety counters are removed on the owners next upkeep)

Nonland permanents with safety counters can’t be sacrificed or destroyed.

So... What now?
