{@C} Jenova, Ancient Calamity [FINAL FANTASY Prerelease Promo][PR FIN 228]

At the beginning of combat on your turn, put a number of +1/+1 counters equal to Jenova's power on up to one other target creature. That creature becomes a Mutant in addition to its other types.

Whenever a Mutant you control dies during your turn, you draw cards equal to its power.
