Secret Santa

Starting with you, each player exiles the top card
of their library face down, looks at it, and then
chooses a random opponent and gives it to them.
As long as that card remains exiled under the new player's control, that player may play that card
without paying it's mana cost.
Choose carefully to whom you give,
they might not always let you live.
Think you trust the one you chose?
A truce, instead, you must propose?
