Twitch Rework Idea

My fury knows no bounds about using the current Twitch and falling to Black Hole 5 (formerly known as Bronze 5), so I'm here to bring a kit more ideal to Twitch's ADC image, since he has little damage output through much of the game. This is due to his dependance on passive stacks, which boost his kit damage, but take far too long to build up considering he is very squishy.

[Trigger Happy] - Twitch permanently gains 30/40/50/60/70% Attack Speed. On cast, Twitch fires 3 minor bolts in a 675D line over 0.5s to inflict 75/120/165/210/255 (+60% Bonus AD) total physical damage on all enemies in the path. The first hit applies on-hit effects. <Mana> 65/70/75/80/85 <CD> 12

[Contaminate] - Twitch's basic attacks passively poison units for 40/80/120/160/200 (+45% Bonus AD) magic damage plus 5/10/15/20/25 bonus flat damage per stack of Deadly Venom. This spell can be cast to inflict 100/115/130/145/160% Total AD on all marked unit within 1000D and stun them for 1.25s while resetting the damage/passive durations. <Mana> 50/60/70/80/90 <CD> 14

[Venom Cask] - Twitch throws a jar of various poisons to the location, inflicting 60/120/180/240/300 (+120% Bonus AD) physical damage on all enemies in a 200D area over 3s and Slowing them by 25% for the duration. Units marked by Deadly Venom are Slowed by 40% for 3s. <Mana> 80/85/90/95/100 <CD> 10

[Ambush] - Twitch passively becomes Stealthed in brush after a 3s delay and remains Stealthed for up to 2/3/4/5s after leaving brush with a 20% Movement buff. If cast under Stealth, the passive bonuses are removed while Twitch recieves 300 bonus attack range and 30/40/50/60% extra Attack Speed for the next 7s. The passive returns after the active bonuses expire. <Mana> 100 <CD> 130/120/110/100

Ability [Deadly Venom] - Twitch's basic attacks reduce the target's damage output by 3% for 5s. This value can stack up to 6 times versus Champions, 4 times versus large units, and 3 times versus all other enemies.
