The Unshaped One

If you paid {w} when casting The Unshaped One,
it becomes white angel with vigilance.
Repeat for {u}, {b}, {r}, {g}, and {c} to become blue sphinx with flying, black demon with lifelink, red dragon with haste, green hydra with trample, or eldrazi with menace respectively.

The Unshaped One enters the battlefield with a +1/+1 counter on it for each different mana color
used in its cost.
