NOTE: forgive me if this isn't completely finished since I'm still trying to figure it out.you may ask, What is rainbow stairwell? well, it's a niche magic(online or paper) format where the deck has to abide by some interesting rules( here: https://mtg.gamepedia.com/Rainbow_Stairwell). After you read those rules, I would suggest you try to build one, since it isn't too hard, and the decks are challenging to build as well as play. building one well really tickles your brain!
