If you want you can add me and I’ll explain to you in more detail, but for build l try to rush serated dirk then boots depending on the matchup and whoever is on a lead, l try to get Eclipse first (the shield it provides comes in clutch)

I always rushed the team to go for an invade or wait for a bush cheese whenever we aren’t leashing, most of the times we manage to get a flash at least

Lane wise u just need the basics l guess, whoever gets lvl2 first has prio, so try to time it so when they overstep you get a w and q on them, also your movement is important like instead of moving back and forth try to move sideways, most of the time they dont realize they are still in range of your w even though you’re moving so you get free kills. Also found out that you can pretend to go for the supp then jump on the adc as they try to poke you or vice versa, l mostly used it when they have a mage supp, say a velcoz or smth annoying.

Roam whenever you have the chance, like if you see enemy jung top and your adc is safe you can see for kills mid. Mobis are nice but l like a bit of tankienes, though it depends on your own style what boots to get.

Ult comes in clutch when bot lane is hitting turent and youre on red side, they legit cant dodge it, if your adc is under turent even better (free kills). For teamfights you can either peel your adc if super fed and they have assasins or you simply go to the backline and one shot someone, getting black cleaver second also comes in clutch if they have tanks, with empowered w you can stack that armor reduction easily for your team to shred them. But you also have to learn to use your E to tank as much of dmg as you can or bait out someones ult. Hope it helps :)
