How Does {semblance anvil} work with {Heliod, god of the sun}? Do all legendaries cost less, creatures cost less, and enchantments cost less? So {emrakul, the aeons torn} would cost less?
Heliod has two Card types: Enchantment and Creature.
Semblance Anvil will reduce the cost of spells you cast that are Enchantments and/or Creatures. Legendary is a Supertype that isn't effected at all.
Thank you! Enjoy your 100th karma!
