Penelope, Friend of Fiends

Hexproof
If a creature you control with power 4 or greater
has haste, Penelope has haste. The same is true
for deathtouch, double strike, first strike, flying, indestructible, lifelink, trample, and vigilance.
Demon, Dinosaur, and Dragon spells you cast
cost {b}{r}, {r}{g}, or {g}{b} less to cast. This effect reduces only the amount of colored mana
you pay.
