Why this duo works

Irelia supplies the hard crowd control and roaming follow-up that Teemo's kit lacks, while Teemo adds magic damage and slows that help her stay on marked targets. Teemo players recommend a roaming mid with reliable crowd control, which fits Irelia's stun and dash resets.

Playing the duo

Teemo's Noxious Trap (R) slows enemies, while Irelia's Flawless Duet (E) stuns and marks them; that mark gives Bladesurge (Q) a reset for her follow-up.

How to play as Teemo

Place mushrooms on river and jungle approaches before Irelia roams; if she catches someone with Flawless Duet (E), your slow and poison add follow-up damage while they are controlled.

How to play as Irelia

Use Flawless Duet (E) on an enemy already slowed by a mushroom, then follow the mark with Bladesurge (Q); Teemo's trap does not replace your own stun or mark.
