Hellsteed text is "The first ally other than Hellsteed to attack during YOUR TURN gets +2 attacks"
So, my opponent had 4 hellsteed on his side of the field. I used Mind Control on a Carniboar that has 2 attack, and it attacked his hero with 10 damage. It wasn't his turn, so Hellsteed shouldn't give the bonus damage.
The major problem is that when he attacked on the next turn with other ally, Hellsteed didn't give any bonus! So I think it considered the Mind Controled ally as the first attacker, even if it wasn't his turn.
