Gold stands for rare, silver for uncommon, and a black expansion symbol means it's a common card
It also allows you to pay three mana and tap it to make a 2/2 that is every type, which is a nice bonus when times are tough, and your hand is non-existent, but thats really not the point here
They are also ideal for games where a Planar deck is shared between all players, where a complete collection is almost a requirement
