This deck was built with synergy in mind. Every card has a purpose, and some cards combo very well with others.If there is some card that you think would fit in better, please leave a comment and let me know.
Combo 1: Rattlechains. Synergy for all spirits to give flash and hexproof. Works very well being held as a counterspell for your creatures, or with Topplegeist to flash in, tapping down one of their creatures.
Combo 2: Spectral Shepherd. Allows for the continuous bounce of Rattlechains and Topplegeist to retrigger their effects. Also another good counter to save your creatures. Works well with Descend upon the Sinful too to save your creatures before you board wipe.
Combo 3: Willbreaker+Any targeting card in the deck. Kill them with their own creatures, and free up targets for your stasis.
Those are the most noteworthy combos in the deck.
The deck is also set up to get delirium as easily as possible.
The planeswalkers synergize just as well as the other cards. Narset Transcendent is useful for all 3 of her abilities. Extra draw power, double the power of your stasis spells with rebound, and emblem to wreck a noncreature heavy deck. Jace, Unraveler of Secrets as well. Extra draw power, remove pesky creatures and slow them down, and emblem to stop them in their tracks. If you manage to get both emblems on the field, it's pretty much game over.
The sideboard is set up to go against creature heavy agro decks Niblis of Dusk and Declaration in Stone, and noncreature heavy control decks (the counterspells).
Again, any suggestions would be great. I have play-tested it quite a bit and have had a lot of success so far. Please +1 upvote if you like the deck and idea.
