Maridia of Sharn

Wild Shape—At the beginning of combat on your
turn, you may have Maridia become a copy of
target non-legendary creature until end of turn,
except its name is Maridia of Sharn, and it's legendary in addition to its other types. If you
do, Maridia gets +X/+X until end of turn, where
X is that creature's mana value.
{5}{p/b}: Transform Maridia. Activate only as a
sorcery.
