Seeing as reb is still managable against combo, why do we cut off four slots of our already crammed sb? Their marginal utility is low because of the number of matchups they are useful in as well as how useful they are in those matchups. As for control, reb is much, much better against blue control and other control decks tend to play a lot of land to cast their expensive spells (making extra dazes weak). Low marginal utility means they get cut from my sb so my other matchups can get better.

Also, test submerge if you think it's weak. I did as well at first, but I tested it and now I understand. It might even be better against loam than relic.
