When Mundo's passive ability triggers during a combat chain resolution, does his Might increase between each card resolving, or only after the entire chain resolves?

Ruling: Mundo's passive ability checks and increases his Might as soon as each spell resolves and enters the trash during chain resolution, not just at the end of the entire chain.

Sequence:

• Challenge is played targeting Mundo (13 Might) against Sett Brawler (15 Might)
• Player responds with 2x Stupefy
• Opponent responds with Discipline (returning to 15 Might)
• Chain resolves in reverse order: Discipline resolves first, then each Stupefy resolves and goes to trash
• Mundo gains Might after each Stupefy enters the trash
• Result is a trade when combat resolves

Nuances:

• Because Mundo's ability is passive, it triggers immediately as each spell enters the trash during chain resolution, allowing him to gain enough Might to survive combat that would otherwise be lethal
