Hi Natoflex!
I don't usually play with her a lot, but it's a deck focused on a casual game. Regarding the performance, it fulfills what I tried to propose, which is to keep your hands always discarding cards, but to have Xantcha as a draw source. Most of the time this favored certain players, helped them to look for their wincons. An interesting detail is that Xantcha has a very aggressive clock, hitting at least 5 per turn, this putting a lot of pressure on the game, especially if she has some power's or infect's enchantments.
Any questions I'm here.
