I've made some changes lately that have been really great. Overall, I'm pretty happy with how the cube has been playing out lately. However, there's a few balance things I'd like to adjust, and I think I can solve that by pivoting some threats and cutting a few cards that just aren't getting there. Here's my rambling thoughts in no particular order:
With the manabase of this cube, aggro should have the ability to reach for the win against 3/4 color value decks
The birthing pod/aristocrat focus of the cube is gumming up the board a LOT
Water Gun Balloon Game, Blast from the Past, and Mirrored Lotus just aren't good enough.
Recent focus has been on building adequate artifact removal. Now there might be a little too much
Artifacts are strong, but very focused on affinity aggro. Haunted Platemail + Pentad Prism could help out wildfire decks AND trading post type decks. Few other cards I've got my eye on too for this
Combat tricks kinda suck, auras kinda suck.
