With my design I was really pushing for Hexproof + Indestructable first and foremost then I was just looking for whatever keyword soup I could get. Most of my keyword creatures are triple ability creatures if they aren't for those protections. I kept a few low cost deathtouchers outside of that as well just because I can use them as early defense in a pinch.
The idea is fairly simple for my first draft. Ramp into commander with as many abilities as possible and then just play a control game of disruption, interaction, and draw. I am seeing a lot of tempo control in my meta right now so being hard to interact with while having a lot of interaction might be nice.
CONSIDERATIONS:
Sylvan Scrying / Expedition Map / Pir's Whim - Just wondering offhand how much I should value Cavern of Souls early as well as some of the means to buff my commander to 3 attack lethal if cavern isn't a concern.
Sylvan Library - With access to a lifelink commander its easier to turn this card into card draw.
Collector Ouphe - I went back and forth on hating on artifacts harder or not. In the end I didn't have much for creature tutors so I opted to run some of the non creature ones over ouphe.
Return of the Wildspeaker / Stinging Study - Just thinking about more draw. I don't have a ton of draw in my deck but my commander does kind of filter the creatures out as draw. The concern with that being if my commander isn't dying much they might get stuck in hand.
Massacre Girl - I had been contemplating if I could get more sweepers in and I saw this card which I have very few sources of Menace. I don't think I could always cast it because it can kill my commander but it might be something that could be cast instead if someone is going fast.
Veinwitch Coven - Menace option and using it as weird recursion could be a thing.
