Start out defensive. No matter what champion you're against, you will deal massive damage with your Alpha strike. Stay behind some minions, until you have Alpha strike, and focus your target's on Minions when the enemy is nearby. Damage the enemy slowly down, and then rush Ignite, Ultimate, and Alphastrike at once. Remember before you get the kill, use your Ultimate! This will gain you Movement Speed & Attack Speed for a limited time, and reset all your cooldowns.

When in lategame, and you see one enemy with really low health (500-800 should be fine for squishy champions) you rush your Ultimate, E Ability, and your Alpha strike at that enemy. When you land the kill, you use Alpha strike on another enemy nearby with low health. Try to land at least one kill for each Alpha strike you use, or at least have your Ultimate active at all time for resetting cooldown on Alpha strike. This will allow you to rush into the enemy with 6 alphastrikes in one teambattle, with like 1000 Damage / Alphastrike.
