Reusable contingencies & conversions you splice into a line.
If your free sac outlet (Zuran Orb) is exiled (milled is the other trick, below), make a sac outlet on the fly:
Replaces "sac all lands to Zuran" with "sac lands to a Scapeshift copy," so the Analyst loop still runs without Zuran. Good vs exile-based hate.
Needs Shifting Woodland + Analyst in GY + delirium + ≥12 mana. Activate Woodland → Analyst, hold priority, activate Woodland → Zuran Orb; let the Zuran copy resolve and sac all other lands; then let it become Analyst and activate to return everything. Repeat if the returned lands beat the next cycle's cost.
Cave turns spare mana into the missing land:
Treat the bounce as a delayed resource:
Always track whether a held bounce has resolved — many lines depend on returning TWest only after enough mana is made.
Repeatable land-sac, but once its ability gives a creature shroud that creature can't be targeted again. Hold priority to sac multiple lands at one target; keep a spare creature (Arboreal Grazer, a Saga Construct, a Titan, Dryad Arbor) to target after Safekeeper shrouds itself. When Woodland is copying Analyst, Safekeeper can target Woodland-as-Analyst.
Tap + threshold to draw 3 / discard 3; ignore the draws and discard the lands you need in the graveyard for Aftermath Analyst.
