Mega Salamence

Flying, Vigilance

Aerilate — During each upkeep, roll a number of
dice equal to the number of creatures you control
without flying. For each crit, target creature you
control gets flying until the end of the turn.

Double Edge — Mega Salamence & other creatures you control with flying have +3/+0 during your turn, but -1/-0 during each other player's
turn.
