Thul, Voracious Doom

Intimidate
Whenever another creature would die, exile it
instead. If you do, put a +1/+1 counter on Thul,
then each opponent loses 1 life for each +1/+1
counter on Thul.
{7}{b}: Destroy another target creature. This
ability costs {1} less to activate for each creature
you don't control.
