Also worth mentioning, Leia is not ideal to use because while the extra hits are nice. They cause Tm issues especially in p2-4, With your current roster, teebo lead, with speed over 145 min, and min 60% potency, wiggs, qgj with omega basic and Rex will work decently well. You want teebo omega for his basic and stealth Rex omega as well on basic, there's no speed down there nor tenacity down which means you want to get potency as high as possible on qgj Rex and teebo as well as get their speeds over 145 , Wedge you want to mod for offense hard numbers and Biggs for speed as primary goals for those two.
Keep teebo stealthed so his basic will remove 100% turn meter, and use wiggs for damage and qgj and Rex for Back up turn meter removal,
