With the Unleashed rule changes, does Monastery of Hirana still work the same with Warmog's?

Yes, Monastery of Hirana and Warmog's Armor still function the same way following the Unleashed rule updates.

The interaction remains consistent because the core mechanics governing buffs and equipment have not changed. Here is the breakdown of how they interact:

1. Triggering the Buff: When a unit equipped with Warmog's Armor conquers, the equipment's triggered ability ("When I conquer, buff me") resolves. The unit receives a +1 Might buff.
2. Spending the Buff: Monastery of Hirana has a triggered ability that activates "When you conquer here." Because the unit has just received a buff from Warmog's Armor, it now has a buff available to be spent to satisfy the Monastery's cost ("you may spend a buff to draw 1").
3. Timing: Both abilities trigger off the same event (the unit conquering). As the controller of these effects, you choose the order in which they resolve. You can resolve the Warmog's Armor trigger first to ensure the unit has a buff, and then resolve the Monastery of Hirana trigger to spend that buff and draw a card.

Important Nuances:

• Buff Persistence: As noted in RiftJudge FAQ #8468, buffs are objects placed on a unit (Rule 702). They remain on the unit until spent or removed. If the Warmog's Armor were to be destroyed or detached after the buff is granted, the unit would retain the buff it already received, though it would no longer gain new ones from future conquers.
• Spending Buffs: You can only spend a buff that you control (Rule 702.2.b.2). Since the unit is under your control, you are able to spend the buff it carries to trigger the Monastery's draw effect.
• No Changes to Interaction: The Unleashed update introduced new rules regarding copy effects, ambush, and battlefield control, but these do not alter the fundamental interaction between equipment-granted buffs and the Monastery of Hirana's ability to spend them.
