Butcher Braxton is finally available in the packs (New Blood excluded). This seems like a good time to go and pay the Judge a little visit... and isn't it a good thing that you are twice as likely of coming by him today?! Good luck to you gunslingers!
Butcher Braxton would be forced to a lower zone on the following conditions:
-New cards in GhosTown appear to force him down (Z Palace only has 10 cards from each Clan plus Legendaries)
-Butcher Braxton needs to have a high usage rate
-Butcher Braxton needs to contribute to the deck having a high winning rate.
Often these conditions are to satisfy balance for the game.
I find it unlikely Butcher Braxton will be forced into a lower zone. He is very weak to SOA compared to Nekron who was placed into a lower zone due him having a similar ability, but a good Bonus to pose a serious threat. In the event Butcher Braxton does get his Regen, Cancel Life modifiers can interfere with him.
Yeah he's hard to face. Especially if you are up in Polit or Z, it's hard to rock an mono Gheist or Roots, running them half makes it difficult to have the bonus on and cards with SOA ability aren't very abundant or are in a clan without many good cards.
