mana regen runes n mastery on poppy and nearly no Magic regen on her after that and just Q E QE QE QE QE in lane infinetly and own.!
Full offence yi, but start cloth 5 and build into wriggles. Ward will be helpful for splitpush and armor lifesteal is okay, cheap price too.
less lifesteal more dmg? mb bilgewater into youmus IE LW or so.Anyway
PUSH LANE TO TOWER, GET DOUBLE STRIKE, GO TO A GUY HIT HIM
Q A CREEP RIGHT AWAY TO ESCAPE! TRYNDA STYLE, MORE DMG, OWNS!
Yi lane or so and rush sheen with armor pen. Op for owning dudes?
Yi jungle. Movespeed tankyness and ability to clear creeps fast. For counter jungling, steal camps run away and control the jungle in general and later just dive people with red buff
yi top or mid watever full dmg runes etc like usual and start with full dmg too. Take advantage of yi dominance, sure sure, but then!
switch to tanky dmg. Like gauntlet, randuims, warmogs etc, last whisper, pd
dunno. Might be cool
