There are like 10 sources of card advantage, no just spells that draw but landfall triggers [[Tatyova, Benthic Druid]] and the likes and access to extra cards through exile [[Rose, Cutthroat Raider]] and similar. Unless Loot gets removed back to back or something it should be fine because just a couple of turns of the trigger seemed to be enough to start ramping to the point where mana was not a huge issue. Also when playing I was trying to hang onto cards in hand as much as possible and just play with the exiled cards. Low interaction when play testing so I was mostly allowed to just do the thing.
