Can you use Arena Bar to put a buff token on a unit that conquered Monastery of Hirana in order to trigger the draw effect?

Ruling: No, you cannot use Arena Bar during a Showdown to put a buff token on a unit conquering Monastery of Hirana because Arena Bar does not have the Reaction or Action keyword, so it cannot be played during a Showdown.

Sequence:

• A unit conquers Monastery of Hirana during a Showdown
• Monastery's effect requires the unit to have a buff token when it conquers to draw a card
• Arena Bar cannot be played at this timing because it lacks the Reaction or Action keyword needed to play cards during Showdowns
• Therefore, you cannot add the buff token in time to get the draw
