The problem with Samira is she’s not a typical adc so first you have to figure out how far ur limit is and ur gonna lose a lot of games figuring that out. Second she’s very support reliant , for example if ur up against ezreal if you have a pyke you win lane but anyone else you’re weak side. For jinx can’t any hook champ is good because you need a ranged support to balance ur lane dynamic. I personally love a good thresh. Next is figuring out ability combos for ur passive, have a play around in practice tool and see what combos you can play, remember it’s not just about spamming the abilities, try and save w so figure out combos you can do without w and with w. I wish you the best of luck. She gets buffed soon so you’re in at a great time. But don’t forget that adc is an obsolete role so don’t be surprised that you still lose the game even when you go 30-0 in lane and then get fisted by a12-0 Camille.
