No Guts No Glory

Sacrifice X creatures.
Lose X life.
Create X tokens that are non-legendary copies of
your commander, with 3 time counters. At the beginning of your upkeep, remove a time counter
from each token and lose life equal to half of the
number of time counters removed this way,
rounded down. When all time counters are
removed, if you have the greatest life total among
all players, you win the game. If you have less life
than any player you lose the game.
