I want to report a bug about card "Aang, swift savior". I joined TLA bo1 play-in, and the bug happened on my last round. I had “Aang, swift savior” and other creatures on the battlefield, my opponent attacked me with his creatures and use “Airbending lesson” (or another card, which can airbend creature, I can't remeber), to airbend my Aang. I was ok with that, and I flashed this Aang back to the battlefield.

However, the ability of this Aang, when he enters battlefield, airbend another creature or spell, hasn't been triggered. I couldn't airbend one of attacker, and I lose the game.
