Alright, Single Combat pack 1. Roalesk was pack 2, and Bolas pack 3.
I was moving towards W/G until Roalesk made me want to splash blue. The problem with my first two games was that I tried to dead-even split Bant, but it would have been better to just splash blue, since I had 3 ways of mana fixing, 2 of which were in green.
I didn't have too much sit in my hand, but I was running too many counterspells for what I was trying to do. I think a UB deck with Davriel, Ravnica at War, and Shadowfugue would be a good place for a stack of counterspells. I pulled them for round 3 and steamrolled my opponent(though, admittedly, they were bad)
Overall I think Selesnya is playable. 5 Teyo's Lightshield's went around. if I was in white and I got 2 Huatlis and maybe a Wanderer, that would be nuts. I would just need some flyers or reach to discourage poking.
Other than that, Ajani would be a good signal.
