Cytoshape

A creature may become a copy of itself this way. This generally won’t have any visible effect.

The creature copies the printed values of the chosen creature, plus any copy effects that have been applied to it. It won’t copy counters on that creature. It won’t copy effects that have changed the creature’s power, toughness, types, color, or so on.

At the end of the turn, the creature reverts to what it was before. If two Cytoshapes affect the same creature on the same turn, they’ll both wear off at the same time.

Effects that have already applied to the target creature will continue to apply to it. For example, if Giant Growth had given it +3/+3 earlier in the turn, then Cytoshape makes it a copy of Grizzly Bears, it will be a 5/5 Grizzly Bears.
