Tap Out

As an additional cost to cast this spell tap any untapped mana producing permanents you control

Target person outside the game may take your place as a player. (They use your hand, library, graveyard, cards you own in exile, permanents you control, emblems you control, counters on you, commander damage applied to you, your life total,
and your seat at the table to play. You are no longer considered a player for this match)
