Vigilance (Attacking doesn’t cause this creature to tap.)
Whenever you attack with three or more creatures, put a +1/+1 counter on target creature you control.
The armasaur was skittish about the lanterns, until it noticed the captivating dance of its shadow along the walls.
It doesn't matter what happens to the creatures you attacked with once Armasaur Guide's last ability has triggered. When that ability resolves, you'll put a +1/+1 counter on the target creature regardless of whether the creatures you attacked with (or Armasaur Guide) are still on the battlefield.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
