Constellation control deck with
Demonic Pact
and lots of bouncy cards.
The game plan is that you get some early game hand and land disruption with Brain Maggot & Spreading Seas and then let the
Riptide Chimera
s cycle your
Cloudform
s, Spreading Seass and
Demonic Pact
s for value.
It's a good idea to keep mana up for Echoing truth or Retraction helix the turn before a Pact kills you, in case they kill your chimeras and/or Daring thiefs. It's preferable to use the creatures though.
The Chimera wants to pick the pact up directly after resolving the third pact effect, you can't pick it up the same upkeep it kills you because the trigger resolves even if you do. The daring thief, on the other hand, wants to exchange the pact the very turn it would have killed you, since this exchange happens in the untap step and therefore avoiding the upkeep trigger, causing your opponent to lose the game on his next upkeep instead.
Between
Doomwake Giant
and the bounce spells you have a fair amount of creature control.
If your opponent has no enchantments the
Daring Thief
s can swap out one of your enchantment creatures, preferably a maggot, for one of their creatures and then swap the enchantment creature back to give them a lethal
Demonic Pact
. You can also use the retraction helix to tap your thief if attacking isn't safe.
The ideal situation is getting a
Daring Thief
manifested under a
Cloudform
, which allows you to both protect it and keep it hidden until the turn you want to swap a pact.
Suggestions for sideboard welcome, I'm not interested in changing the main game plan because I think it's really fun, but please try to improve it.
There are some obvious things I need from the sideboard. I need something to swap out
Extinguish All Hope
and
Doomwake Giant
for against decks with few or no creatures. I also need something to replace Spreading Seas against blue decks. I also need some kind of graveyard hate.
