The new Phage opens up a host of interesting potential upgrades, and the only reason I don't use it right now is it only builts into Trin Force, which is of limited use for a lot of the champions I play. I've come up with some item concepts of my own to work with it, primarily focusing on combining it with Tenacity, as the two passives look like they'd interact well together to help fighters and marksman chase mages and other people with lots of cc.

I don't think it'd be necessary to combine it with Executioner's Calling (thought that useless pocket knife of an item desperately needs some sort of rework. I think the root of the problem is the Avarice Blade). Chasing and counter-healing don't go as hand in hand as you'd think, considering the most prevalent form of healing in the game at this point is Lifesteal, which benefits from straight up brawling more than running away.
