Flying, Ward {1}

When you cast a non-Pokémon spell, Corvisquire gets +1/+1 until end of turn. Then put a shielded counter on target artifact or Pokémon. (If it would be damaged or destroyed, remove a shielded counter instead.)

Evolve from Rookidee {1}{W/U} (Cast this as an instant for {1}{W/U}. If you do, your Rookidee is sacrificed as it becomes Corvisquire with a +1/+1 counter.)
