Picked for what they do in Greel's deck. When two cards do the same job, the one with the lower comes first. All of them fit Greel's color identity.Mana ValueThe total amount of mana a card costs, all added up. A card costing two generic and one green has a mana value of three. Wizards renamed this from "converted mana cost" in 2021, so older cards and articles may still use the old name.Open the full glossary
Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryBPlayers write colors as letters: B for black.Madness/DiscardDiscard decks throw away their own cards on purpose and play cards that reward each discard. Cards with madness can even be cast for a different, usually cheaper, cost at the moment you discard them.Open the Madness/Discard pageOpponent DiscardMakes opponents discard cards from their hands.

A flip that can only hurt you, like the one on Mana Crypt, does not count, because no deck is built around it.
