You can do a tier 9 grind now without having to supplement your silver supply with a bunch of extra premium tank games to buy the tier 10 assuming you sell the 9 . <| sep |> I ' m obviously flexing my biased but why on earth are people up in arms about mox opal . Affinity can ' t have a rock but eldrazi get to keep their sol land . And everyone playing red green white and blue have the option to one sided wipe and possible eat my lands . I thinking getting rid of mox opal prevents the deck from playing ahead of its ubiquitous removal . The only busted thing it gets to do is play the t 1 cranial plateing , which is actively eliminated by a well placed removal spell . people at my local shop and at tournaments throw games against affinity all the time because they don ' t see that the deck is a bunch on 11 ' s that don ' t have a bunch of lords , it ' s char belcher like it asks the question of removal and if not gg . It dies to fair decks way to easily and every color has options that make the game one sided in their favor .
