Each opponent loses the gameNear-infinite lifeloss
How it works
Cast Hatred by paying 3 and by paying life equal to the highest life total among your opponent, causing any other creature you control to get +X/+0 until end of turn, where X is the life paid this way.
Activate Jarad by paying 1 and sacrificing the creature, causing each opponent to lose life equal to the creature's power.
Each opponent loses the game due to having zero or less life.
