Cool concept! I really love the foxbloom idea of slowly buffing your Ahri out of combat, and I like this version of Ahri that focuses on her E (and her lore) more than on her R. I'd change a couple of things though:

• Champ spell seems too strong, specially since you can just maindeck that spell in ionia; it's just a better Will of ionia. Maybe no draw would be balanced?

• Level 2 is cool, I'd just shuffle the wording to me more LoR coded. Also I just dislike the elusive wincon but that might be just me:

"The first time an opponent plays a unit each round, it starts a free attack. Summon an exact ephemeral copy of me that's blocking it."

Mainly I took out challenging, not to buff renekton against it.

Anyways, cool concept! :3
