I got a three big ones I think are slept on
Brim on Icebox - Ok hear me out, you still need a viper for defense, but he's actually so OP for attack if you can get bomb down without man disadvantage. The postplant molly buys so much time, and the stim is also perfect for attack because attack on icebox you're just running back and forth in spawn during the midrounding
Sage on Bind - Wall for safe plant on A, the slows are really good to stop site hits and floods, and having a sage heal midround + the skye heal is so nice. (just don't be named ardiss)
Brim on Ascent - not having the omen blind is tough, but the smokes last longer and the molly / ult are really impactful
