You play JG Aatrox because Top is a pain to play and also because its hard to snowball and win the game with just yourself. Playing JG sovlves so of those issues. Its a fun pick that can win multiple games if you play Flank-trox right.

Red start: passive proc the red and walk back to Q sweetspot and aa between Qs. Goto rapters and auto the big one then E in the corner and do the same thing. Goto wolves then blue + gromp. You can do blue and gromp and the same time but its risky because you can get invaded and die.

Blue start: go gromp, wolves, rapter, red using the passive proc and E auto reset as much as possibe. You must hit Q sweetspots or your clear is gonna be hella slow.

You can easily get scuttles with Q + Smite + AA

Tips:
2 points in Q early speeds up your clear.
Control ward Blue side if you're starting red.

You have to play like an Assassin or you'll be completely useless. Wait till your team engages or enemy team engages before you go in. With Duskblade, It'll be very to kill you if you're playing right. Killing the carries is essential to this strategy.
