Does the Volibear legend trigger when you play a 4 Might unit directly on Trifarian Warcamp?

Ruling: Yes, Volibear's legend ability will trigger when you play a 4 Might unit on Trifarian Warcamp. The unit resolves to the battlefield and Trifarian Warcamp's passive ability applies the +1 Might instantly, so Volibear only ever sees it as 5 Might.

Sequence:

  • The 4 Might unit resolves to the battlefield
  • Trifarian Warcamp's passive ability applies +1 Might instantly (no chain, no delays)
  • When Volibear's play effect registers the unit as resolved, it sees it as 5 Might
  • Volibear's legend ability triggers

Nuances:

  • Trifarian Warcamp is a passive ability, not a trigger, so it applies immediately with no chain
  • This is similar to how Darius sees himself as the second card played in a turn
