Enchantment
If a creature would enter the battlefield under a player's control except the first one during each of their turns, that player sacrifices it instead. If the player sacrifices it this way, they return another target creature card in their graveyard to the battlefield. If the player doesn't sacrifice it this way, they return another target creature card in their graveyard to their hand.

Secretly enchant anything visible from your seat
When Costume Change enters the battlefield, secretly note anything visible from your seat. Note the order. (Make two choices. The first is secretly enchanted, the second is noted.)
Sacrifice this, reveal your choices: Swap them until end of turn. (One becomes the other and vice versa.)
If Costume Change would leave the battlefield, instead put it in the secret zone. (Hide it, it doesn't exist. Neither does the secret zone.)
