Its easy to go to MTGA or play a pre-release and dont even think about older cards, but sit for a game of Commander, and suddenly half of the cards on the battlefield look like they come from different games
Aether Meltdown, Imprisoned in the Moon, and Unquenchable Thirst look to be inferior to Spontaneous Mutation, although admittedly I havent played with any of the three yet personally
Black You are willing to go all out and sacrifice everything for victory
Any deck that cares about party or tribal will be happy to take this Changeling, and the right decks can really take advantage of it
A combination board of Matron with a Lackey in play both gets you any goblin you need and lets you play it for free (provided the Lackey doesn't have summoning sickness)
If you tilt the card at an angle, the surface shouldnt shine like a cheap gloss
