Missing sideboard cards? The full 15-card sideboard runs about $35.85.
Buy sideboard on ManapoolOcelot Pride Midrange is a go-wide token deck with Orcish Bowmasters punishing your cantrips, so you need cheap, efficient answers rather than more card selection. Into the Flood Maw lets you bounce Ocelot Pride, Ajani, or a Cat token at instant speed for one mana, resetting their life-gain/token engine and buying tempo. Poxwalkers' 3/1 body dies to their wide board of Cats and doesn't block profitably, so trim it along with some of your weaker looting since they'll be targeting your hand with Thoughtseize and Cabal Therapy anyway. The extra Unmask helps you strip Swords to Plowshares or a key piece before they can deploy their disruption.
Dimir Tempo has no graveyard hate in its main deck, so Leyline of the Void is strong here. If it's in your opening hand it starts on the battlefield without being cast, which sidesteps Force of Will and Daze. It also exiles their cards instead of letting them reach their graveyard, which stunts Nethergoyf and its escape. Bridge from Below is weak here since it mostly matters when you're racing, not when you're fighting through Force of Will and Daze; cut it since the Zombie tokens won't close games against a deck that can just Wasteland your mana or counter your payoff. The extra Unmask helps strip their Force of Will or removal before you commit to your graveyard plan. Keep Cabal Therapy in to rip Force of Will or Thoughtseize before they can use it.
Sultai Aluren is a glass-cannon combo deck that doesn't interact with your graveyard, so this matchup is about who assembles their engine first rather than grinding; Poxwalkers and extra discard-fodder matter less than speeding up your own kill. Silent Gravestone can come in as a cheap artifact that doesn't slow your plan much while protecting your Bridge from Below and Narcomoeba triggers from any incidental graveyard hate they bring in (Faerie Macabre). Kiora's Dismissal can bounce their Aluren or Omniscience back to hand on your turn if you're ever racing and need to buy a turn, since both are enchantments. Prioritize goldfishing your Cabal Therapy/Dread Return kill as fast as possible rather than boarding for interaction.
