Sukut, Sands Of Pestilence

Creatures with -X/-X counters have decayed.
Indestructible
Whenever a creature you don't control would get
-X/-X it gains twice -X/-X, and whenever they
would gain X -1/-1 counters, they gain that many
-2/-2 counters instead.
{t}, Add {b} or {g} to your manapool if a creature
died this turn, otherwise add {c} to your manapool.
