Chardalyn Dragon

A colorless 4/4 flier for six is a plain rate anywhere; the reason to name this Dragon rather than run a nameless flier is the two card types stacked on its line. As an Artifact Creature, it slots into the colorless shell any deck can play, feeding artifact-count payoffs and metalcraft-style engines while still counting as a Dragon for the roster of tribal lords, tutors, and cost-reducers built around the type. That dual membership is the whole design brief: a Dragon that splashes into a five-color or artifact build without a single pip of commitment, where a red-costed Dragon of the same body would be locked to its color identity. The flavor comes from the Icewind Dale lore of the Frozenfar, where chardalyn is the enchanted black gem that drives artifice to ruin; the creature is a construct given the shape of a wyrm, which is why it reads as Dragon and artifact at once rather than either alone. Strip away the tribal and artifact context and it is filler, a French-vanilla flier whose only text is evasion. The case for running it is subtractive: it asks nothing of your mana, so the cost of inclusion is the card slot, and it pays that back in whatever your Dragons or your artifacts already wanted to do.
