so this was a first and cost me a game. I played a tess with reska on the board, and one of my tess spells killed the reska and reska took over my tess but after reska took over my tess, all the things tess played played for his side.
This is not a bug, it’s the intended interaction. It works the same way with O.G. Yogg.
From the HS wiki: If Yogg-Saron changes ownership during its Battlecry, such as by one of its spells destroying an enemy Sylvanas Windrunner or by casting Psychic Scream, or self-targeting with Treachery, the rest of its spells will function as if the Yogg-Saron was played by the other player. For example, effects targeting the casting hero will target the opponent, while effects targeting an enemy minion will choose a minion belonging to the original player, and AoE effects like Arcane Explosion will affect the original player's own board. The developers consider this "too cool to not keep"
This is the exact same scenario. Substitute Reska for Sylvanas since it’s basically the same effect.
It’s definitely surprising if you don’t know the interaction when you experience it. I thought I was losing my mind the first time I had a Yogg psychic scream after which I got faced by a pyroblast from the other side.
That’s hilarious. I’ve seen some weird bugs like this as well but I don’t bother to report them because I think it’s so hilarious and rare that I keep them under the radar.
While this one may not be a bug, I have seen things that for sure are. One offender right now is Habeas Corpses.
