Ivern masteries?

So yesterday my Pathfinder session got canceled, and since I was pretty bumped I decided to spend some IP I wasn't using and get Ivern. Dude is...weird as fuck. I successfully counterjungled a for a bit, but we ended up losing because there wasn't much I really knew how to do. His W (Bush) is really niche imo and I feel it would be better as his E since I kept accidentally pressing it instead of his shield in fights (Sion main reflex). I tried running TLD, but honestly I didn't feel like I could proc it off with his abilities. I also kept summoning Daisy too late and she dies with Ivern so...I should summon her earlier.

So what masteries have you guys found workable?
