Description

Agatha of the Vile Cauldron (PWOE-199p) is a legendary Human Warlock promo from Wilds of Eldraine. Her static ability reduces the activation costs of activated abilities of creatures you control by an amount equal to her power, but cannot reduce those costs below one mana. She also has a paid activated ability that grants other creatures you control +1/+1, trample, and haste until end of turn.
