Miran, the Ledev Wolf

Companion — Each creature card in your
starting deck shares the creature subtype Faerie.
(If this card is your chosen companion, you may cast
it once from outside the game)
If you cast Miran, the Ledev Wolf while Vio, Selesnyan Knight is not on the battlefield, the
mana cost of any Faerie is reduced by 1 {w} or {g}.
