MTG

I got curious, so I checked the CR:

205.3g Artifacts have their own unique set of subtypes; these subtypes are called artifact types. The artifact types are Attraction (see rule 717), Blood, Bobblehead, Clue, Contraption, Equipment (see rule 301.5), Food, Fortification (see rule 301.6), Gold, Incubator, Infinity, Junk, Lander, Map, Powerstone, Spacecraft, Stone, Treasure, and Vehicle (see rule 301.7).

Looks like Terminus does not show up, and "Infinity" and "Stone" are separate subtypes oddly. I guess their digital clients are just doing whatever they want.
