Groundbreaking Glider

Trample, Doublestrike
{3}: Punch Jump: Groundbreaking Glider gets
flying until end of turn.
{2}: Finishing Punch: If Punch Jump was activated
this turn, Groundbreaking Glider gets +2/+1 and
menace until end of turn. If it attacks, the creatures
that block get 3 stun counters.
With powerful punches, the groundbreakers, a creature
that should not be able to fly, can jump high and then
glide, going island to island. They have been seen
fighting multiple enemies at once with both arms.
