Of course, my terms would be having Pauper (a specific constructed format where only Common cards are allowed in ones deck) and Singleton (a constructed deck format where ones deck may not contain more than one of any individual card) always available formats, but they do show up as special events
Just look at Niv-Mizzed, Guildpact, a five-mana five-colour 6/6 with Flying and Hexproof from multicoloured that lets you deal damage, draw cards and gain life if youve got colour pairs among your permanents
From the main menu of the game, you will be able to look up, in an orderly fashion, all the cards you have in your possession
Sure, it can give you cards and direct attacks elsewhere
These charts are invaluable for understanding a cards long-term performance
