2 cards that did not live up to expectations removed and 2 new cards added to strengthen the weaker archetypes

Judith, the Scourge Diva is removed and replaced by Havoc Jester in a attempt to slow down the BR deck a little

Acane Infusion and Thermo-Alchemist were not good enough and not seeing enough play and were therefor replaced by Experimental Overload and Exalted Flamer of Tzeentch to make the UR deck more resiliant over time

Bitterblossom was too good and therefor removed and replaced by Dreadhorde Invasion

Oni-Cult Anvil, Vega, the Watcher and Mishra's Research Desk were removed, they did not play as intended and didnt see enough play.

Conjurer's Closet was added to make the UW blink deck stronger

Noose Constrictor was added as another discard outlet for the RG deck

Knollspine Invocation is being tested, its added for the RG deck but might be too strong with Squee, Goblin Nabob
