This is basically a greedy Kerendon Glasshopper deck. The main weakness is that of all Glasshopper decks - you kinda NEED to pledge for it to work at reasonable efficiency, otherwise your
Silverwing Couriers are vulnerable to
Torch.
I might just be lucky but it's been very reasonable in PvP (I usually relegate it to casual).
This is my favorite of the decks I've built that are capable of pulling off
Dread loops.
I gave it a whirl in Gauntlet and it's actually surprisingly good - gauntlet doesn't deal very well with
Telut, Queen's Hand or
Azindel, Revealed.
This deck can be extremely satisfying for the "Timmy" MtG player archetype when Telut, Azindel, and
Pit of Lenekta get going.
