Broly, Legendary Saiyan

This spell can't be countered.

Double strike, trample, vigilance.

When Broly, Legendary Saiyan enters the battlefield, destroy all nonland permanents with
mana value 1 or less. For each permanent destroyed
this way, you get that many energy counters.

At the beginning of your upkeep, you may skip your
draw step. If you do, proliferate twice.
