Post-rotation GWU morph deck. This deck has been doing well against a variety of different match ups.
Trail of Mystery
is a beast. Mass deck thinning and land tutoring, smoothing out draws and later manifests, plus giving all my creatures a build in combat trick.
Mastery of the Unseen to pump out a constant supply of face-down creatures. Plus, against certain match ups, the life gain makes it next to impossible for my opponent to win.
Whisperwood Elemental works as an additional source of face-down creatures. Plus, being able to "replace" face-up creatures with a fresh batch of face-downs is icing on the cake.
Den Protector
is always a solid card, whether recalling a card at just the right moment, creating an endless cycle of Den Protectors recalling other Den Protectors, or simply being an unblockable attacker.
Stratus Dancer doubles as an evasive creature and a counterspell to any board wipes.
Icefeather Aven
for bouncing other troublesome creatures, reusing my own morphs, or saving something from an untimely death (just to be able to morph it again).
Ainok Survivalist
is there for any decks relying heavily on artifacts or enchantments.
Hidden Dragonslayer
also serves the role of additional creature destruction if needed.
Reality Shift is wonderful removal against practically any creature, especially Hangarback Walker,
Haven of the Spirit Dragon
recursion, and anything indestructible.
Cancel fills the roll of your run-of-the-mill, no fuss counterspell. Will probably be replaced with whatever Cancel variant comes out in BFZ.
