Dimir Tempo's plan hinges on Force of Will, Daze, and Thoughtseize disrupting our combo turn, so proactive discard that strips their answer before we go off is excellent. Thoughtseize also has no downside against a deck full of free spells and cheap interaction. Cabal Therapy is often a dead draw before we know what to name and costs a creature for flashback, so it comes out in favor of unconditional discard. Memory's Journey is the weakest card selection piece since we rarely need to rebuy graveyard pieces against a deck that isn't grinding us out with graveyard hate.

Ocelot Pride Midrange races us with an explosive token board while also carrying Thoughtseize and Cabal Therapy of its own, so we want to be the ones disrupting first. Thoughtseize can strip Orcish Bowmasters or removal before we commit to the graveyard plan, which matters since Bowmasters punishes our cantrip/draw-heavy sequencing. Cabal Therapy is cut since it's often a blind guess early and costs a creature on flashback, a tempo we can't spare against an aggressive clock. Memory's Journey is unnecessary since Orcish Bowmasters doesn't interact with our graveyard combo pieces the way true graveyard hate would.

Sultai Aluren carries its own Thoughtseize plus Snuff Out and Force of Vigor as sideboard disruption, so proactively stripping their hand with our own Thoughtseize before committing to the combo turn is valuable. Cabal Therapy is a weaker choice here since it's a blind guess and costs us a creature on flashback that we may need for our own graveyard plan, so it's cut in favor of unconditional discard. Memory's Journey isn't needed since this matchup isn't decided by graveyard denial. Keep the rest of the combo shell intact, since Sultai's clock from Ignoble Hierarch into Craterhoof Behemoth or Natural Order lines means we still want to be as fast as possible.
