First, my main build, this can work in every game.

This deck is really good when you are in a game with a strong backline or a lot of burst like a 2dps + 2 healer or 2 dps + 1 flank. You can survive longer when you go flank and easily return to the rune in case of burst or focus. The cooldown reduction on the rune allows you to often harass the backline when it's difficult to take a kill.

This deck has a lot of hp to survive from sniper headshot and never get one shotted when you are against strix or kinessa. The movespeed allow you to go fast in the backline to kill the sniper, and versus bad and medium player its hard for them to shot you. The lifesteal card can help you against tank but cauterize hard counter this so its not the most important card here.

This deck is really strong for harass and snowball when you are destroying the backline. The speed allow you to chase enemy and taking kill easily. Kill the damage first with your overcharge burst and then abuse of speed and DR to chase and kill the support without overcharge, go back to your rune and help the backline if the enemy flank is here or go kill the tank.

This deck is really fucking strong in low elo because trash player never get cauterize so you can abuse of that and be really annoying and hard to kill.
