Does the Discipline keyword count as a buff that can be spent for Monastery of Hirana's effect, and how does it interact with permanent buffs?

Ruling: Discipline is not a buff. Only permanent +1 might counters are considered "buffs" for game mechanics purposes. Discipline provides temporary +2 might that is removed at end of turn.

Sequence:

• Discipline grants +2 might for the current turn only
• At end of turn, the +2 from Discipline is removed automatically
• If you spend a buff (permanent +1 counter) to draw from Monastery of Hirana, the unit returns to its original card stated might when the turn ends
• The permanent buff and temporary Discipline bonus are separate mechanics

Nuances:

• Stand United causes all buffs to give +2 instead of +1 for the turn, but this only applies to actual buffs (permanent +1 counters), not to Discipline or other temporary might increases
• Stalwart Poro's shield counter is a buff and would benefit from Stand United's effect
