Thorin's Last Stand

Selesnya can test it as a flexible sideboard card, but four mana is far behind Broadside Barrage's 43-rate interaction and makes the pump mode clumsy.

Could be wrong if Artifact/enchantment targets or token-heavy white decks may become much more prevalent than revealed context indicates.

The modes are functional but inefficient: four mana Naturalize effects and combat pumps compete poorly with Pioneer’s cheaper, established answers.

Could be wrong if A new go-wide white shell could value the modality enough for a small sideboard role.

Wear // Tear scores 62 at a far lower cost, while a four-mana nonlethal pump is too slow for Modern’s usual sideboard and maindeck demands.

Could be wrong if An unusually resilient token deck could use this as a one-card finisher and hate piece.

Legacy has much cheaper artifact/enchantment interaction; this lacks the efficiency or unique effect needed to displace it, unlike Force of Vigor at 83.

Could be wrong if A metagame unusually centered on artifacts or enchantments could create a narrow budget sideboard use.

Elves can use a team pump, but four mana is a major constraint and the removal mode is much slower than Pauper’s efficient artifact hate.

Could be wrong if If go-wide creature decks and artifact targets both rise, the two modes could justify sideboard copies.

Token decks can convert the instant-speed team boost into a meaningful attack while retaining removal utility, but it is inefficient beside Beast Within (66).

Could be wrong if Multiplayer board stalls may make the alpha-strike mode more valuable than its rate suggests.

Instant-speed +2/+1 to the whole team can decisively win combat or finish games; artifact/enchantment removal gives it a useful fallback despite four mana.

Could be wrong if Unknown format speed, token density, and artifact/enchantment prevalence determine whether it is premium or merely situational.
