Tawnos, the Toymaker

The tribal choice here is the whole design, and it is an odd one: Beasts and Birds are two creature types that almost never travel together, which means this legendary artificer does not attach to a single existing archetype so much as ask you to assemble one from scattered green fatties and blue fliers. The copy clause is where the artifact matters. Every duplicate arrives as an artifact token in addition to being a Beast or Bird, which quietly folds a token-doubler's worth of value into an artifact-count subtheme: metalcraft, artifact sacrifice, affinity, anything that reads the board for artifacts counts each copy. The 3/5 body is defensive by intent, not aggressive: it blocks the ground and shrugs off small removal, banking the turns a copy engine needs to compound rather than trying to end games itself. Structurally this is the Green-Blue instruction to go wide with your best expensive spells rather than to protect one threat, and the type restriction is what earns the power. A copy trigger with no tribal fence would be a staple. This one asks you to commit to a wing-and-claw creature base narrow enough that many decks never offer the payoff at all, and that narrowness is the whole trade: you have to build the zoo before Tawnos does anything, and only then does the doubling pay you back.
