Does Abandoned Hall's effect count as "choosing" a unit for the purpose of triggering Irelia, Fervent's ability?

Ruling: Yes. When a player activates Abandoned Hall's effect and selects a unit to receive +1 Might, they are choosing that unit. If Irelia, Fervent is chosen, her ability triggers, giving her a total of +2 Might (+1 from Abandoned Hall and +1 from her own ability).

Nuances:

• Abandoned Hall's text "they may give a unit they control here +1 Might" requires the player to actively choose a unit from among those they control at that battlefield.
• This is a player-made choice, not a programmatic selection by the game.
• Irelia, Fervent's ability triggers "when you choose or ready me," which is satisfied by the player's selection for Abandoned Hall's effect.
• Note: FAQ #4758, which previously ruled this did not count as choosing, has been deprecated.
