This is the new Blightsteel Colossus, an 11/11 indestructible trampling behemoth that effectively has Infect, and practically nothing short of exile can stop it
As such most control decks simply supplement their deck with the odd pure card draw spell to smooth curves or act as top quality filler and are able to function pretty well without any of the pure form at all
Opportunities for fine-tuning include adding the fourth Grisly Salvage (the card is just insane here), a fifth discard spell, Haakon, Stromgald Scourge (might be too slow), Stinkweed Imp or Golgari Thug (depends on their effectiveness on the battlefield), some creatures with unearth (Dregscape Zombie, Rotting Rats, and Scourge Devil all look fitting to a certain degree and therefore are worthy to be at least considered), and so on
Both decks are good fun to play, but in very different fashions
Its not hard to set up a huge attack just by casting noncreature spells
Its far from the premier Amethyst Ruby Bounce Control deck though, so keep that in mind
