Colossal Voidhulk

You can't cast non-Void permanent spells.
When Colossal Voidhulk dies, create three 3/3
black Void creature tokens with fragmentize.
(When a creature with fragmentize dies, exile it and
create a number of 1/ 1 black Void creature tokens
equal to its base power.)
At the beginning of your end step, exile Colossal Voidhulk unless you control another Void
permanent.
