Rin and Seri, Inseparabler
The original Rin and Seri, Inseparable rewarded a Dog for your Cats and a Cat for your Dogs, two bodies pulling in opposite directions across the same board. This riff collapses that duality into a single creature and a single mangled pile of types: every Cat you control becomes a Dog too, every Dog becomes a Cat, and the tribal lines fuse until they are indistinguishable. The pun is rendered entirely in templating, the kind of self-referential punchline the silver-border tradition specialized in, but built to function inside a black-border shell. The haste rider is what saves it from being pure novelty: fold two tribes into one and then hand the entire board a swing the moment it arrives, turning a static type-mangler into a genuine aggressive clock. Two hybrid pips keep it castable, letting a Naya-leaning shell reach it without hard-committing to all three colors at once. Strip away the reference to its namesake and the card falls apart into a two-mana 3/2 granting haste to a pair of creature types it also happens to fuse together for you. Read beside the original, it is less a power piece than a designer riffing on their own naming convention, a wall-of-mirrors gag that only makes sense because the straight version already exists to be twisted.
