Astral Projection

Flying, hexproof
When Astral Projection enters the battlefield,
choose a target creature or planeswalker you
control. Astral Projection's power and toughness
are equal to the power and toughness of target creature or are each equal to the number of
loyalty counters on target planeswalker.
