Triumph of the Masses

Creatures you control get +1/+1, and have
trample, lifelink and haste.
When Triumph of the Masses enters the
battlefield, exile each creature with power
greater than the number of creatures you
control.
{r}{g}{w}: Triumph of the masses deals X damage
to each creature with power greater than X,
where X is the number of creatures you control.
The gathering has no name, no precedent. There
is only hope and unity.
