Maggott, Symbiotic

When Maggott, Symbiotic enters, create two 1/1
black Mutant Insect creature tokens with "This
creature can't block." and "Whenever this
creature becomes tapped, each player mills a card".

Whenever an Insect you control becomes tapped,
exile up to one target card from a graveyard.

Whenever a card is exiled from a graveyard,
Maggott gets +1/+1 and gains trample until
end of turn.
