This is a mirror-style race against another combo deck holding Force of Will and Daze, so proactively stripping their Doomsday, Dark Ritual, or Force of Will with Thoughtseize before they can protect their own combo is very strong. Cabal Therapy is less reliable here since it can't stop them once Doomsday resolves and costs a creature we may need for our own kill. Memory's Journey isn't needed since neither player is meaningfully attacking the other's graveyard. Keep the combo package fully intact and prioritize being faster or disrupting on the front end.
