Archmages Charm is extremely pushed, a solid permission spell, a good way to build card advantage for hitting land drops, and a fantastic tool against Deaths Shadow, Wild Nacatl, Goblin Guide, Pyxis of Pandemonium, Champion of the Parish, Aether Vial, Delver of Secrets, Hardened Scales, Amulet of Vigor, Benthic Biomancer, Glistener Elf, Noble Hierarch, Viscera Seer, and sometimes even Hexdrinker (just to mention a few)
Kodama of the West Tree is a mythic rare, so you won't likely see it
Youll also passively hate graveyards, not to mention slow most graveyard loops and sacrifice decks
Still, it only takes a few wheel effects or mass draw spells to churn out an end of days number of insect tokens
Its sure to become the most collectible item of Disney Lorcanas first year
