Yes, if you are Ragnaros then Tess replays all your Rogue cards. There was even a strong meme deck once in wild running Majordomo & Tess where the idea is to have Tess play Vanish and Cloak of Shadows and then on every turn that follows you replay Tess + hero power until you kill the opponent. The deck was also running Kingsbane to avoid fatigue (Tess would also replay that and you would end up with multiple copies of it in your deck)
Nobody even bothers to read the card text before discussing... "replay 5 cards..."
5 cards is not infinite regardless if your hero class.
No no, we read it. You lack imagination.
If rogue is no longer a rogue and plays a second copy of Contraband Stash, alongside no more than 4 other rogue cards... contraband stash will play itself, and just maybe... go infinite, breaking the game.
