So quite simple, follow the item set and runebuild and focus on building pressure trading damage in bottom lane. Whenever you're pushed in and have secured the prio in bottom lane, make sure to roam and use the mobility of the build to gain ur team kills and objectives. For the Item Set, you can go for the enchantment items to buff up your adc or apc after the Core facilities. Enjoy, it's a hell of fun and a good alternative!
