Vorthos, Steward of Myth

Unlike most abilities that reduce the costs of spells, Vorthos’s ability cannot be applied to generic mana costs. For example, a spell that costs {2}{B}{G} to cast would instead cost {2} to cast. One that costs {4}{U}{U} would instead cost {4}{U}.

If a character has gone by different names, you may count all versions of that character. For example, choosing Lim-Dûl will offer you a discount on (SPOILERS) The Raven Man. Choosing Urza will offer you a discount on (SPOILERS BUT VERY OLD ONES) Blind Seer.

Vorthos’s ability applies to any spell in which the chosen character’s name appears in any form, whether that’s possessive (e.g. Teferi and Teferi’s Protection), or a related word (e.g. Avacyn and Avacynian Priest), or a word that’s derived from their name (e.g. Niv-Mizzet and Izzet Charm).
