Notes
 
Alright, this is a full 360-card cube built around “woodland critters” — animals, forest spirits, fae-adjacent beings, and cozy-but-deadly nature vibes.

Power level is ? creature-forward, synergy-driven, and draftable without needing deep MTG history knowledge.

Theme rules I followed

Mostly animals, beasts, birds, insects, wolves, bears, deer, squirrels, frogs

Nature magic, food, +1/+1 counters, go-wide tokens, mutate

Minimal “humanoids”

No Eldrazi, Phyrexians, robots, or city stuff

A little whimsy, a little savagery

WHITE (50) – small animals, protection, flicker
BLUE (50) – birds, frogs, fish, krakens, tricksy animals
BLACK (50) – scavengers, nocturnal predators
RED (50) – foxes, wolves, rage critters
GREEN (60) – heart of the forest, THE SQUIRREL KINGDOM
