When Switcheroo swaps the might of Mundo (who has 16 might from 6 base + 10 cards in trash) with Student (who has 2 base might), what are the final might values after Switcheroo resolves and goes to trash?

Ruling: After Switcheroo resolves, Mundo will have 3 might and Student will have 17 might. Mundo's passive ability continues to apply, but the -14 might reduction from the swap also continues to apply until end of turn.

Sequence:

• Before swap: Mundo has 16 might (6 base + 10 from trash), Student has 2 might
• Switcheroo resolves: Mundo gets -14 might (the difference needed to reach Student's 2), Student gets +14 might (the difference needed to reach Mundo's 16)
• Switcheroo goes to trash (now 11 cards in trash)
• Final calculation for Mundo: 6 base + 11 from trash - 14 from swap = 3 might
• Final calculation for Student: 2 base + 14 from swap + 1 from spell being played = 17 might

Nuances:

• Swap effects apply as a combination of might increase and decrease, not as a transfer of actual might values
• Mundo's passive ability is always active and calculated in the same layer as the might reduction from Switcheroo
• The -14 reduction persists until end of turn and is calculated alongside Mundo's passive in every might calculation
• All might alterations are handled in the same layer, with additions applied before subtractions
