Elden Lord Rising

Put a commander into play from your command
zone, or search your library and graveyard for a
legendary creature card, reveal it, and put it into
play. Then shuffle your library. That creature
has "You cannot lose life. If this creature would
be put into your command zone or graveyard
from play, you lose the game instead."
Fateful hour — If you have 5 or less life, that
creature has haste, vigilance and indestructible
until end of turn.
