Anyways, Wizards never really understood how to make hosers in the early days of the game
Theres an important distinction to make first, though: some of these are printed in BLC , not in BLB
in some packs you may find Serialized Elven, Dwarven, or Human Sol Ring cards, and only one English-language Collector Booster in the entire world will contain The One Ring (Serialized 1 of 1) card
Its possible that some time in the future of Standard the mana dries up and we see mono-colorless or close to it pop up, or a single card gets printed that makes a deck in an Eternal format tighten up its mana, but odds are until more sets are printed with this mechanic, mono-colorless isnt much more viable than it is now
This should just highlight how close the green cards all are in this list
