msem-instigator

Counter target spell. If that spell is countered this way, exile it instead of putting it into its owner's graveyard.

Destroy target creature that's not enchanted and isn't an enchantment.

This turn, players can't search libraries, bring cards from outside the game into game zones, or move cards that began the game face down in the command zone out of the command zone. (An unlocked puzzlebox cannot be unlocked again.)
Draw a card.

Enchant player
At the beginning of enchanted player's end step, gain control of a permanent they control.

Return target instant or sorcery card from your graveyard to your hand.

Counter target creature spell unless its controller pays {2}.

Return target permanent to its owner's hand.
