Fire of Orthanc

At four mana and sorcery speed, this is far less efficient than Brotherhood's End and is unlikely to earn a competitive artifact, land, or combat slot.

Could be wrong if A dedicated red land-destruction shell could value the incidental alpha-strike turn more than expected.

Wasteland makes a four-mana land answer untenable, while the artifact mode is far too slow; the falter rider rarely offsets that rate.

Could be wrong if A fringe red prison or creature-combo list could use the combined land hit and combat window.

It can hit artifact decks or a land while forcing ground blockers aside, but Dust to Dust is dramatically more efficient artifact hate and four mana is a major cost.

Could be wrong if If red go-wide decks become established, the falter turn may make it a useful niche finisher.

A land or artifact answer that can enable one decisive ground attack has a real niche, but four mana sorcery-speed single-target removal is replaceable.

Could be wrong if Combat-focused red decks may prize the dual-purpose finishing effect more than optimized lists generally do.

Destroying a land or artifact while blanking ground blocks can create a strong attack, but four mana sorcery speed makes it poor when behind or without a board.

Could be wrong if Unknown set speed, token density, and red archetypes could make its falter mode either a frequent finisher or marginal.
