Chrono-Lord Deios and Hand Cannon interaction

With Chrono-Lord Deios and Captain Crowley in play, attacking with Hand Cannon makes the Cannoneers fire FOUR times.

I would expect that at the end of the turn, but I did not expect it upon attacking with Hand Cannon. Wording is vague, but I guess Cannoneers firing is always considered an “end of turn” effect, even when it is from Hand Cannon.

Just like the paladin minions, cannoneers are considered an “end of turn” effect even when triggered in the middle of a turn. Deios doubling that is logical when viewed at through that lens.

Not a bug, just a weird interactionin the underlying rules of the game.
