Any thoughts on critique/improvement?

[Ringbearer]

Focus a lil more on one goal. Either go for fast with memnites and orni's but add cranialplatings as well as some affinity creatures, or focus more on the big bullys.

EDIT: There's a lot of free artifacts.

Even with a bunch of free cards, I strongly dislike playing more than 60 cards in decks, it dillutes consistency. I'd cut the redundant card draws, like Gambit, and the "cute" ones like Infiltration Lens, Spellbook and Infiltration Lens. Also, I'd probably cut Islands for Glimmervoid and other artifact lands, even off-color ones, for affinity purposes. Somber Hoverguard is also a pretty solid creature.

Any particular reason not to just play Affinity?

Any particular reason not to just play Affinity?

That's actually a good idea. There's too much proliferate that's tied to the Overseer, and if I'm running affinity I ought to cut all that and add four Myr Enforcers and two more Frogmites.
