Gruul War Chant: When I first read this card, I thought it was a sorcery and that it was a pretty weak Falter, but I could see trying it out
These sorts of cards are easy to miss, because it seems like you already understand what the card does, but the nature of multiplayer Magic naturally lends these cards a lot of complexity
As far as flavor goes, I like that Andril, Flame of the Wests abilities represent how Aragorn used the sword to get the Dead Men of Dunharrow to fulfill their oath
Black mana, for example, is drawn from swamps, and is parasitic and destructive, leeching power from its victims before destroying them completely
Giving utility at any point in a game, the option for fetching color or just having generic is great
Im sure youll agree its a stellar piece
