Think of them as card draw spells that store the drawn cards in your exile zone rather than your hand
Elite Trainer Box 9 packs plus a Zarude foil promo, 65 sleeves, dice, energy and a storage box
This might not seem like a lot, but currently if you cast a Ruinous Path early in the game then thats all you get from that card
They are custom made by me and are not going to be exact replicas, although I try to get them as close to the real cards as possible.
However, if Null Profusion entered first and then you unlocked Steaming Sauna, you would have no maximum hand size
These card choices are similar to the ones from Pepeteam, who finished fourth in the first post-rotation Magic Online Challenge
