Pfft. This is an easy one to answer, play Tristana to win! She is a strong carry who can shred tanks and take on the enemy adc with ease.

Just the typical adc runes. 3 Attack Speed Quintessences, 9 Magic Resist Glyphs, 9 Attack Damage Marks, and 9 Armour Seals. There is a slight room for variation with the Quintessences; you could take 3 Attack Damage Quintessences since you can reach nearly max attack speed without the Quints late game but it is not recommended as it is better to have more attack speed to multiply the damage on your E.

Always max E first, as it is your main source of damage. Max Q second because it gives you a strong attack speed bonus. Your W last because it only deals minor damage and has a reset anyways.

Typical adc summoner spells, Heal/Flash. Cleanse is also acceptable especially against an Ashe or Sona lane. Some people prefer to take exhaust and let the support take heal but I prefer heal personally.

Tristana is my favourite adc to play into Vayne. I know a lot of people struggle against Vayne and Tristana is a great champ to play into her because of her disengage and burst potential. In ranked

Pros: Tristana has a HUGE escape with a complete reset on it when she kills or gets an assist on someone! Big sometimes unexpected damage on your E. E is good for getting kills and trades. Attack speed steroid. Ultimate is an escape, displacement and high damage. Free cost on Q. Good trading.

Cons: Scales off of AP on ult and W. (E scales off of both). Relatively high mana costs. Pushes lane when last hitting. Passive can make you miss farm. Short range at lower levels. Long CD on Q at early ranks. Rough mid game if you aren't fed. Very farm reliant.

Why are you looking at this? DONT JUNGLE WITH TRISTANA!!

Tristana can be hard to farm with sometimes, but once you're used to it you'll be fine. Tristana is a very farm reliant champion, if you fall behind your mid game will be even rockier, but with good farm you'll be able to carry much more easily.

Overall, Tristana is an awesome AD Carry. She is a personal favourite of mine and very fun to play, practicing and playing Tristana can be VERY rewarding due to her high potential.
