Wrapping up this massive updated with red.
Here again, some sacred cows must go : wildfire, grim lavamancer (even if I love them), splinter twin (many other 2-3 cards combos entered the cube).
Several cards are on the verge, or being tested.
Goblins.dek suffers a bit to make room for other archetype-centric cards, but it likely still a contender (and definitely still fun). Ardoz is for example a premium addition to the roaster.
