I dont write many reviews but I tried this one in once scenario in a lvl 0 Sefina deck with Rod of Carnamagos
If this works like I think it does, this card is absolutely bonkers and it probably needs to be clarified soon.
At this point everybody knows you can do a Carnamagos during a skilltest. Thing is as far as I was able to understand it, tokens from Carnamagos are ignored for the test and could work for this since token you choose need to match an ignored token. It does not specify it would have to be one you revealed by Breath's effect. This would mean for 1 charge one of the 2 tokes you revealed by breath need to match one from a total of 6 revealed tokens.
Its almost certainly not intended but the only way I see it potentially not working is if those ignored token still need to be there on the table when you are choosing which one to ignore. The ones from carnamagos go away after it resolves and honestly I am kind hoping thats the case as I think this would be healthier for the game.
Even ignoring all of the above it still has a ton of utility.
-As mentioned before, the 9 charges is a huge boon. We had a chance to test how this works with Spectral Shield in practice and it made a nearly dying guy almost unkillable.
-It does let you attack with your head endlessly (since spending the token is optional)
-Last but definitely not least is suprisingly the reliability of this thing. If there is a single token in the bag you absolutely do not want to draw, spending just one charge guarantees you dont have to deal with it. Most of the time this will be the autofail, but some scenarios you just have a token which can progress doom or do some worse things if drawn.
Under normal circumstances its hard to pull of extra damage, but if you think of it like a safe way to deal one damage for 1 action, it does look very decent.
