Zangief, the Red Cyclone must be blocked if able. As long as it's your turn, Zangief, the Red Cyclone has indestructible (Effects that say "destroy" don't destroy that permanent. An indestructible creature can't be destroyed by damage.). Whenever Zangief, the Red Cyclone deals damage to a creature, if that creature was dealt excess damage this turn, that creature's controller sacrifices a noncreature, nonland permanent.
