First of the possible many updates trying to support the Artifact and Tokens matters cards, that look very fun and a great way to play one of my favorite cards in Woodland Champion.

Using the Pioneer Masters downshifts.

Besides that, I'm not using cards post MH3, because Wizards stopped printing cards in Portuguese, and I can't have that language limitation stop my playgroupd from playing with the new cards. So from now on, I'm using cards from m15 until mh3, and future downshifts. Maybe I'll build another cube with rares too, who knows.

Armored Scrapgorger and Undead Butler are slightly different cards than the swapped but both trigger Insidious Roots, with Butler triggering twice.
Black removal is heavily associated with life loss now, and only a few sources of lifegain, to balanced a bit more the removal.
