Moritte of the Frost

Cloning has always chased flexibility: you become the best creature on the board and inherit whatever it does. This shapeshifter instead treats the copy as a growth mechanic, bolting three riders onto the process that change what the copy is worth. Two extra +1/+1 counters land whenever the copy is a creature, so duplicating your own body is a strict upgrade rather than a mirror image; that counter clause turns off cleanly when you copy a noncreature artifact or enchantment, which keeps the ability from collapsing into a flat "everything gets bigger" button. It also makes the copy legendary and snow, feeding snow-matters payoffs and permanent-counting that a plain Clone would ignore. The changeling rider is where the reshaping actually happens: a copy of any creature now carries every tribe on its type line, so it slots into whatever tribal engine your board already runs regardless of what it copied. That clause only comes online when you copy a creature, because copying overwrites the printed text and the exception has to grant those types back explicitly; declining to copy leaves a 0/0 that dies on resolution, so the ability is functionally always aimed at something. Vesuvan Shapeshifter and the Clone line before it are the obvious reference points, but where those designs prized adaptability, this one prizes accumulation: the copy is not a snapshot of what you already have, it is a bigger, snowier, every-tribe version of it.
