Yordle Kennen

Kennen takes Gargoyle Stoneplate, Ionic Spark and Sunfire Cape, prioritising durability over raw damage since his job is to survive long enough to land repeated stuns. Ziggs goes Guinsoo's Rageblade, Red Buff and Void Staff for sustained area damage, Veigar takes Hextech Gunblade, Rabadon's Deathcap and Spear of Shojin for burst, and Fizz rounds out the team with Jeweled Gauntlet, Striker's Flail and Hand Of Justice as a flexible crit AP assassin.

Yordle count augments, anything that grants a free Yordle copy or bonus stats per Yordle, are close to an auto take in this comp specifically, since the trait rewards raw unit count more than any other trait on this list. Otherwise take econ first, then AP or attack speed augments to push your four carry backline further.

Poppy, Teemo, Tristana, Lulu, and Rumble are largely interchangeable Yordle bodies you swap in and out based on which copies you find, and any of them are cheap enough to hold items early while you build toward your core four carries. Kobuko and Yuumi can fill the same role a little later.
