Rohgahh, Kher Keep Overlord

Kobolds have been a Magic in-joke since the earliest days: 0/1 red creatures with no mana cost, printed as a curiosity and largely ignored by every deck that wasn't building around the joke itself. What this design does is take that punchline and wire an engine around it. The anthem clause turns those bodies into 2/3 attackers, which is already more than the tribe ever asked for, but the more interesting mechanism is the pair of cast-triggers that link the two tribes at the point of casting rather than at resolution. Cast a Kobold spell, pay the , and a 4/4 flier lands alongside the Kobold you cast (nothing is sacrificed; the token arrives on top of the spell itself). Cast a Dragon spell, and a fresh Kobolds of Kher Keep drops onto the board. The wrinkle is that both triggers key on casting a spell, not on tokens entering, so the Kobolds and Dragons this card makes do not themselves fire the other ability; there is no self-sustaining loop, only a reward for keeping actual cards flowing from your hand. That distinction is what keeps a two-tribe engine honest. It converts Kobold density into Dragon quality and rewards a deck stuffed with cheap Kobold and Dragon spells, not a single lucky trigger. It is a rare case of a payoff that scales off cards originally built to have no payoff at all, which is precisely why it only functions as the centerpiece of a dedicated build.
