Zulura, Grand Oblivivore

If Zulura is on the battlefield under its owner's
control or in the command zone, abilities your
opponents activate that cost {0} and spells they
cast that cost {0} both cost an extra {1}{p/u}{p/b}.
If an opponent casts a spell without paying its
mana cost, counter that spell unless that player
pays an additional {1}{p/u}{p/r}. Then, scry 1.
Whenever an opponent sacrifices a permanent,
put a +1/+1 counter on Zulura.
