Demons Everywhere I Look (Standard)

Using Emergence Zone to flash in either Liliana's Contract or Arcane Adaptation on the opponents end step, and with everything being demons, you win on your upkeep. All creatures are 1-ofs so any 4 will count for the contract. As much scry, card draw, and surveil as was cost effective on creatures, to cycle through deck and find the enchantments to win. Several slight secondary wincons built in, while still building towards main wincon - Persistant Petitioners, you can use Arcane Adaptation to call everything advisors instead of demons. Mill the opponent. Can bring in Etrata the Silencer to exile 3 of opponents creatures to win, from sideboard. Can just go wide and zerg opponent to death with weenies (lots of avoidance in the creatures). Can bring in Jace from sideboard if you are going to deck yourself. And in the exact right rare situation, you can even use arcane adaptation to call everything rats and swing big with rat colony.

I am bad at sideboarding against meta threats, but I threw in an elderspell and a few others just in case. Masterminds Acquisition to either answer a threat from sideboard, or to pull the enchantment you are missing to win. And 1 copy of each of the 2 main enchatments in sideboard so that something like Unmoored Ego cannot lock you out of it.

Feel free to leave advice or criticism. Have not had a chance to test it yet.
