Skyseeder

Flying
Whenever Skyseeder attacks or blocks, create X
0/1 Egg creature tokens, where X is Skyseeder's
toughness. They have "{2} or tap a creature you
control: deal 1 damage to this creature. Any
player may activate this ability" and "{0}: If this
creature has 6 or more toughness, exile it and
create a token copy of Skyseeder."

The odds against the eggs are great, but the numbers
of eggs are greater.
