This is the best kind of a deck: a slow value deck
On the flip side, you want the front to be completely see-through
A two mana 2/1 with the Vipers ability is a pretty nice two drop for Limited, as it is reasonably likely to chip in some extra damage all game, so the fact this can also bounce something is nice Cleave Shadows is certainly somewhat situational, but I think youll be surprised by how many board states there will be where it lets you kill something
This is an excellent way to protect your own things, but it does have a small drawback, and thats because it doesnt say Creatures you control. That means that even your opponents things will be protected if they happen to be playing the same tribe or just some cards that share a type
However, because this Imp isn't a legendary creature, one has to stand to assume that just like Uncle Istvan, "Norritts" are just a type of creature, a sub-type of imps
