Unbounded Potential is a sweet card for counter synergy that I wanted to fit in to the last update. We can de-power removal a bit, and Ossification can be a little complex to track.

Skyship Plunderer's ability is relevant now, so swap it back in.

Drown in Ichor is interesting with proliferate, and -4 actually kills more things than non-black.

Evolving Adaptive is good, but confusing with the influx of +1/+1 counters. Swap it out for Kessig Prowler which also has the capability to grow later on.

Being able to split Candy Trail's cost over 2 turns is nice, as is a little incidental lifegain, but I would rather have another proliferate source from Tezzeret's Gambit.

Eternal Taskmaster isn't appearing in a lot of other cubes anymore, but Victimize is, so let's test it out.

The Shatter mode of Abrade hasn't seemed to be used very often, so the card selection from Fire Prophecy is probably better.

I haven't seen Twinferno played a lot, and Inspired Tinkering has been great, so Big Score might be another interesting card for the big red decks.

I've been wanting to get Saddled Rimestag back in for a while, because it really seems like green's best aggro 2-drop. Taking a step back, Beast Within just seems terrible when compared to all other removal spells, so it can go.
