Knight-Kenser, Rot-scion

At the beginning of each upkeep, each player
discards a card, loses 2 life, and sacrifices a
permanent.
Whenever a creature or land you control is
targeted by spells or abilities your opponents
control, that player loses 3 life and sacrifices
a creature.
"He is a stain, a blight on Eldraine that simply
cannot be removed simply." - Kenrith
