Palladia and Arcades

Whenever a creature you control would switch its
power and toughness, that creature gets +X/+X
until end of turn instead, where X is the
difference between the creature's power and
toughness.
Whenever a creature you don't control would
switch its power and toughness, that creature gets
-X/-X until end of turn instead, where X is the
difference between the creature's power and
toughness.
