Donatello, the Brains

Donatello is a 3cmc 2/4 that augments all token creation under your control by adding a free Mutagen token alongside every batch — a replacement-effect token doubler-adjacent that scales multiplicatively with token generators. Signature in tokens-go-wide strategies where each token spell or trigger produces an additional Mutagen token; Character Select Partner means he pairs with another TMNT commander to unlock a second command zone slot. His impact is proportional to token density in the deck, making him fringe outside dedicated token shells.

• Donatello's replacement effect triggers on ANY token creation, including treasures, food, clues, or creature tokens — but the added Mutagen token is a specific named token type, so understanding what Mutagen tokens do in context (likely tied to other TMNT cards) is critical to evaluating the combo ceiling.

• Character Select Partner (mech-partner) is a TMNT-specific variant of the partner mechanic that only pairs with other cards that also have 'Character Select' — it does not combine with generic Partner or Partner With commanders, so deck construction is constrained to the TMNT card pool for the dual-commander setup.

• Because the replacement effect says 'those tokens PLUS a Mutagen token are created instead,' it cannot be chained with itself — doubling season effects that copy the replacement would still add only one Mutagen token per batch, not a recursive loop.
