Call of Confusion

Dinosaur creatures you control get +1/+1 until
end of turn. If you control 4 or more dinosaur creatures, they gain trample until the end of
the turn. If you control less than 4, they gain
lifelink. If you control 10 or more, they gain
both. If you control 2 or less, create a 3/3 green dinosaur creature token with trample. It's effects
are negated. It's sacrificed at the begging of your
end step.
