Force of Will is a clean safety valve for a lot of the more degenerate things going on in the cube: discarding and reanimating a Griselbrand on T3, curving into Embercleave, etc. It can also be used to protect degenerate blue cards, which should be fine. I think blue can benefit from this effect and its an iconic and powerful card that will encourage people to get into blue. Sublime Epiphany was pretty cool, but at 6 MV and compared to Cryptic Command and Mystic Confluence it didn't really see much play.
Pyrokinesis is a tough one. Right away with this cube I recognized the danger Fury posed to heavy creature-based aggressive strategies especially when paired with some of the reanimation available in this cube. It not being a creature helps. Red is already in a very good spot in the cube and while I worry that the addition of Pyrokinesis will further hamper GW tokens, I think it is more safe for the current environment than Fury. If it proves to be to problematic I will switch it out for either Flare of Duplication or Mine Collapse.
Malevolent Rumble is a card whose existence I just discovered and other than being a sorcery, it seems to be all around better than Grapple with the Past. They have been swapped.
Other Thoughts
I have been wanting to give blue and red free spells for awhile now but was debating what the picks should be. While I am not sure either of these new additions will stay in the cube, I do want to test them and see if they are too powerful in their respective colors.
I am concerned with the power level of green being too low. While I think Green has good tools available to it, it does lack many payoffs or enablers for GW tokens specifically compared to its other archetypal cards. I am considering several powerful options to bring in to see if they can help boost the overall playability of Green and GW tokens.
I have gotten to play cube 3 times in the last month! That's triple last year already, so I am thrilled. Games in the cube have been feeling good recently with the exception of a few games of GW but I'm confident I can bring that playability up.
Until next time!
