[Solved (not a bug)] Bug with Ashamane and Vanish

I don’t know which one is bugged or both. In Standard: a Warrior found Ashamane (with Marin) and got all the buffs of Kil’Jadean; later when I used Vanish (found with Dreamplanner Zephrys) the Warrior got the cards with the buffs but I didn’t.

That gave a massive advantage to the opponent, which flipped the outcome.

[Solved(not a bug)]: It’s Ashamane was probably working correctly, and the Warrior probably used Ashamane cards the second time.

You mean your vanish didn’t remove the KJ enchantements on the ennemy minions it returned back to hand ?

No I figured it out (I didn’t confirm it but it sounds too possible). They probably used Ashamane cards they got before the Vanish and they happened to be the same/similar with the old ones so it confused me. Massive high roll though.
