There have been a few issues building in the cube for a while so I'm going to try to address them all at once! I have no idea if any of this will actually work, but hopefully it will be fun to find out! We'll start with the gold section to inform the rest of the decisions made.

I think counters is probably the strongest thing for that color pair to do in this format, but it's kind of parasitic. Luckily MH3 gave us some great counters cards, so we can expand a little in that direction.

At the same time, -based tokens have been a bit strong lately, so I am pivoting to an equipment strategy. The equipment from and counters from help solidify the power 4+ theme, and there are also some cards that care about "modifications" in general, so counters can help that out too.

Shifting focus further away from tokens, gets some cards that care about re-using creatures CMC <= 3 and ETBs.

As the actual control color pairs in this format, and get some actual control cards in their gold sections.

Due to various token cards getting cut, Saheeli, Sublime Artificer is coming back in as a card, so Third Path Iconoclast comes out for Balmor, Battlemage Captain, who can support her, Young Pyromancer, and Murmering Mystic.

And finally, though Bloodbraid Elf is undeniably a great card, it has nothing to do with the monsters theme (and really encourages playing a much lower-to-the-ground deck), while Writhing Chrysalis (well-known for terrorizing MH3 drafts) both helps you ramp out a monster, and is, itself, a creature with power 4 (as well as some incidental counters).
