Szeth, Nightblood's Keeper

Flying, deathtouch
If Szeth, Nightblood's Keeper dealt damage that
would destroy a creature, exile that creature
instead.
Whenever Szeth, Nightblood's Keeper deals
combat damage to a player, that player discards
that many cards at random and you lose that
much life.
If an ideal you control is destroyed, flip Szeth, Nightblood's Keeper.
