- Mordenkainen's Polymorph will overwrite any previous effects that set the creature's power and toughness to specific values. Effects that otherwise modify the target creature's power and toughness will still apply no matter when they took effect. The same is true for +1/+1 counters.
- The creature doesn't lose any of its abilities.
