Gavin, of the Eight

Undying, Vigilance. Before the start of the game, if Gavin is your commander, create a sideboard with
all the cards with "Tempting offer" and "Council's Dilemma" that aren't red cards.
Once per turn, you may Suspend a nonland card
from your hand that doesn't already have suspend,
with X time counters where X equals that cards
CMC+1. Eminence-Whenever a Suspended card
you control runs out of time counters, cast a
random card from your sideboard then remove
that card from the game.
