Kupa advice?

Finally ran into the guy with my ranged tactician on ultimate. Took me about 10 mins and 2 deaths to take him down. I am just not sure what to do against him at all. Facetanking is impossible since the just blood pools outheal my damage and outdamage me despite mythical warborn and 25% lifesteal. Kiting takes forever, with one mistake and you’re missing half of your hp. I have absolutely no idea how I would deal with him as melee.

Any advice on how to do better against him?
