Early Game:

If you get a Lurking Fear start with that if you can’t get that start with Carrion Collector. For me I found the most successful matches started with me going second and dropping a Lurking Fear followed by two Carrion Collectors. This will let you snowball stupid fast later.

Mid Game:

You hopefully have gotten two discounts by your third turn and can drop some cheap Nekomata or  ideally  Klaxon. Anything else you should just play to apply pressure and because its cheap or will make whats left even cheaper. while this is going on drop any extra mana on things that generate Shadow Creeps.

Late Game:

Now you have either killed your opponent by overwhelming them early  or you have around 10+ Shadow Creeps. Now you want to stall with Munch and  Desolator while you wait for a n Obliterate or a Ghost Azalea if you’re close enough.

Notes:

Everything else in the deck should just be used to follow this plan and accelerate the game while pacing yourself to line up for the kill.
