As the title says, been having a lot of success with this build. Takes a little skill to pilot the early game but once you navigate this part and curve out properly with your influence it's fairly autopilot.
Worth noting that you should really focus on when to play Ixtun. Don't let it sit as a discover card if you don't have a way to 5/6 power.
You have three modes for it:
-Give a unit a big stat buff. However, your only have merchants before turn 5, so often it doesn't really hit well.
-Draw two weapons from the void. However, you have 7 weapons in the whole deck. How often are you redrawing more than one, and is that real value? This mode is very much a late-game sort of effect.
-Fast speed polymorph. This is useful admittedly, but I think there are many spells that do this much better; Avigraft or Vanquish main are much "harder" removal options that I think do more.
However, if you have a Merchant, its power goes up dramatically. You can use it as a trick with your Merchant for a massive 12 point life swing and eating an attacker/blocker, or you can use it on an attacking creature to let your merchant eat it. Furthermore, its late-game potential card advantage is still there when you need it, without worrying about having to set up if you don't already have weapons in your void.
