Gilanra, Caller or Wildwood & Akroma, Vision of Ixidor - the result is Gilanrakroma, Keyword Soup. Mono-white w/ the benefit of Green Ramp & Card Draw. Fun casual deck.
When I first got into commander I looked at all the commander options and decided I'd do partners. The ones I picked were Bruse Tarl and Thrasios, your number 1 and 2. Later I picked up Ishai to put with Bruse (as you mentioned, nice combo there). Later I got Ravos, your number 6, and now I'm thinking about partnering it with Tymna as a better lifegain option. Bruse Tarl has been my primary piece for a fun time. Glad to see you're on exactly the same wavelength!
I’m rockin Ich-Tekkek and Livio right now after seeing your golem tribal deck. I was stuck between Livio or Akroma but I think the flicker is more valuable
