1. Thing in the Ice   Board Clear against Aggro!
2. Chasm Skulker With the the draw power from Forgotten Creation and all my instants this card becomes a scary threat that your opponent is forced to deal with before Thassa, God of the Sea or Slip Through Space lands on the field.
3. Forgotten Creation Has synergy with Chasm Skulker and helps with win conditions from cards like Jace, Wielder of Mysteries and Thassa's Oracle. Also fattens up the graveyard to help with high cost delve cards.
4. Thassa, God of the Sea Not sure if I'm happy with this in the deck yet but it does help me with getting good card draw while threatening unblockable creatures.
5. Thassa's Oracle Step 1: Throw deck in Trash. Step 2: Play Thassa's Oracle and Win.
6. Jace, Wielder of Mysteries Just another win con of self mill while giving me another draw option. The fatter my hand the more work Forgotten Creation can do.
7. Mission Briefing With all the self mill this card makes sure that all of my instants are just as dangerous in my graveyard as they are in my hand.
8. Opt and Slip Through Space fill the same role in cheap draw cards but Slip Through Space gives me lethal presence with a fat enough Chasm Skulker.
9. Search for Azcanta   I like the pre-draw "surveil" it offers to help fatten my graveyard for delve mechanic while keeping me from drawing dead.
10. Treasure Cruise who doesn't want to draw three cards with Chasm Skulker and Forgotten Creation.
11. Ominous Seas With all the draw power of the deck this seems like a no brainer.
12. Stern Dismissal To remove threats that can help buy you time for mid game set up.

Looking forward to some feedback and suggestions!!!
