Tryndamere AP Top
IT's about burst. but the cool-downs are so low that you can spin > auto attack > spin > auto attack.
Use your spin as your gap closer and best attack, make sure to hit all minions if its just minions. or make sure to go through champs.
use your R for survival and the rage to heal yourself. always use q to keep health at full. even if you have no fury.


Master YI AD Top
Its all about hitting hard and fast, make sure you get your crit to 100% meaning the last phantom dancer can be another item but the attack speed and crit.
use R and E to take town players.
only use E against turrets unless your desperate.
Dont ever heal using w unless your hidden, its not as good against champs as AP master yi.
However since the patch its worth getting at level 3.

Morgana AP Mid
Use W to harass and kill caster minions, use auto attack to last hit front minions
Use Q then W on a champion as quickly as you can.
Save E for you and your team mates don't hesitate to save another team member, use q to slow them if you can.
Use r after you have gotten off a q and w on a champ, auto attack and use e on yourself if they can attack you.
by the time R is finished you can use Q and W Again.

Ezreal AD Bot

Ezreal is Ezreal just use q to kill minions instead of poking, then kill players when you want to.

Soraka AP Support
You can priority mana regen(E) and silences(E) for Ezreal early game and then focus heals later, or you can build both together.
Some Ezreal's dont need the mana(E) as much as they need the heals, so go all heals(W) apart from level 2 make sure you have E anyway.

Use your Ultimate in team fights before anyone drops if only one person is getting attacked use W instead.
