Nice deck. If I may offer some advice, however, putting
Ultimate Price into a sideboard might be a good idea, as there aren't a lot of monocolored decks when compared with the shards decks, guild decks, or just multicolored decks. Also, if you're running
pack rat, putting some draw spells in to sustain it might be a good idea. Maybe you could use the space from sideboarding
Ultimate Price?
