Fable of Wolf and Owl

Cast a green spell, take a 2/2 Wolf; cast a blue spell, take a 1/1 flier. That is the entire engine, and it asks for nothing in return: no activation, no tax, no payment beyond the spells you were already casting. The two halves are deliberately not interchangeable, which is where the design earns its keep. Green builds a wall of ground bodies; blue builds a clock of evasive ones, and a deck spanning both colors gets a different token from each spell it casts. A deck leaning on cheap interaction and cantrips quietly assembles a board over several turns, while a velocity deck chaining one-mana spells can convert a single turn into a swarm. The "you may" clause is a small lever rather than a bluff: the choice matters when an extra body would feed an opponent's payoff (a death-trigger engine that profits from your creatures dying), or when you would rather not commit a token into an obvious sweeper turn. The hybrid pips let the enchantment function in a single-color shell yet pay the most to a deck spanning both. It belongs to a lineage of enchantments that turn spell-velocity into permanents, and it does so with a gentler hand than the all-or-nothing storm payoffs that came later: the reward scales with how many spells you stack, but it never punishes the slow draw, and it never forces a token you do not want.
