Radagast, Wizard of Wilds

The token payload here pays you for a deckbuilding decision most token-makers punish: it triggers off expensive spells, not cheap ones. Every cast of mana value five or greater hands you a fixed modal choice, a 3/3 Beast or a 2/2 flying Bird, which means the engine sits naturally in a big-mana, ramp-heavy Simic shell rather than the go-wide swarm most Beast and Bird generators want to live in. That inversion is the interesting part: you build up rather than out, and the tokens are a rider on your top-end payoff spells, not the plan itself. The reward is flat rather than escalating; a seven-drop makes the same single token a five-drop does, so the design leans on casting many big spells over the course of a game, not one enormous one. The ward package underneath is a coherent second thought, granting ward to the very Beasts and Birds this card is minting, so the board it builds is also the board it protects, with the legend's own ward guarding the engine. It is a modest tax, not a wall, but it stacks with the type-matters grant into a self-reinforcing loop: cast big, make a creature, protect the creature, cast big again. The 3/5 body is built to endure rather than pressure, which suits a card that wants to survive to its fifth or sixth land and keep casting the naturalist's slow, additive value.
