Those 3 new cards are definitely interesting, the first on its own will propably be almost unplayable, given the massive amounts of removal people run and a 3 point body being extremely low.
However with Organics (which there is no other incentive to run in masses thus far) it can reach 2 points per turn, which is regular Gernichora Slyzard value (which has 1 more point to remove, 1 less provision and blocks the Fruits from being used elsewhere) and can be protected with Avalach and Eredin to actually enable a functioning deck.
A 3 point body, cooldown of 2 and reduced by specific cards played.
This card is a better elven swordmaster, if you can run enough organic cards (which seems to be a monster thing).
+ if its an vampire it has synergie with other cards and probably bloodmoon (which is not revealed yet)
So i suggest waiting a little. Its probably a better elven swordmaster and that card sees a lot of play.
