How hard is twitch

I still need a secondary ADC and mid to carry bronze. I know who I'm taking as my secondary. Vel'koz. Obviously I have shitty mechanics and I'm a decapitated chicken my current ADC is mf. I hear pros recommending twitch for lower elo. He's a safe ADC because the stealth escape unless they got within meele range when you used the invis. He's a hypercarry and since games and late in bronze and people throw, that means he can just keep farming and killing untill he has his core items and boom. His w is an ape poison. His e is a splitshot. His ult gives penetrating bolts and gives him a long range attack. Mechanics don't decide everything though. Eve is mechanically easy but a hard champion to play. Is he hard.
