double feature mtg cards Cathar's Call [Innistrad: Feature] haste.Whenever Olivia Stormcarved Coast [Innistrad: Double Feature]

Whenever you cast a noncreature spell, you may pay

If this spell's additional cost was paid and the revealed card is the chosen type, put that card onto the battlefield instead of putting it into your hand

Just for the added Mana acceleration) If protection pieces are your next target, consider adding in Flawless Maneouver, Coppercoat Vanguard, Lena, Selfless Champion or Boromir

Give a creature double strike for the turn

If your deck leans heavily on graveyard synergy (like self-mill or loops), make sure you also pack answers to graveyard hate and keep backup win plans available

If saccing three artifacts for Salvage Titan is a big deal then losing five for this is going to be super hard work
