Curious how you've been feeling about Xantcha. Recently I discovered that if the opponent I give her to dies/concedes she comes back under my own control (meaning her ability deals me damage now). With no way to sacrifice or otherwise get rid of her, she has the potential to be a liability.

When I get her in play it's amazing though I admit.. gives me a great way to filter my superfluous mana into card draw... but with recent deck additions I'm actually concerned about xantcha's place. (Rakdos the Showstopper has made his grand entrance as a group slug deck... my opponent controlling xantcha dying puts me in direct huge risk of dying very shortly after.)

Bloodytrailz, I think that is incorrect...I believe she would just go into exile when the controlling player dies. I don't think there is a game state rule that would switch control back to you. I'm curious where you heard this!

She has been functioning great! She is a subtle punisher card. Because the targeted opponent can draw cards too, she doesn't generate too much animosity until their life total gets really low.

The only card that is problematic is Homeward Path . If your playgroup runs that a lot, you may want to reconsider her.

No homeward paths in meta thankfully but according to this official ruling, she comes back to us after the controller leaves as if she were under a mind control effect.

No Revel in Riches to go with Smothering Tithe ?

Revel in Riches makes you a target, and the last thing this style of deck is trying to do is paint a big red target over it's own head.

Smothering tithe alone gives us ramp and the ability to tap out our mana and hold treasures for instant speed shenanigans if they are needed.

I am trialling both Smothering Tithe and Revel in Riches in mine. Funny thing about my meta is that both are seen as janky, and not powerful. I haven't gotten to play them, but I am hoping to steal some games with it, or at least hold off some board wipes that could eliminate my possibility to win. Not sure Revel will stay, but I figured that it was worth the try.

Archangel227, Smothering Tithe and Revel in Riches certainly combo well together. However the probability of having them both at the same time is low. The cards would need to be great independently to make the cut. Smothering Tithe definitely qualifies as a ramp engine. Revel in Riches seems more situational. It would be great in a "death matters" deck. I may add it to my Yahenni deck that is along those lines. Thanks for your suggestion.

A weekend of testing showed exactly that, MegaMatt13. Already out with Revel.
