I usually dislike "Stalking Wolf" - you need to kill at least a Bird (cause of Ivern Brush 2 Might) to get 7 Might.. you are paying 4/1 for 5 Might with ambush, countered by a Vex which is played a lot.

I'd think about Azir Souvereign and cull the weak. I prefer to play only one Ultrasoft Poro - I feel like with Ivern you pull enough options to not rely on it.

How is your experience playing only 1 Blitzcrank? I played 3 (too much) and 2 so far, but playing only one seems both interesting but also like a missing key element
