Welcome to my version of a prison deck in the modern format. Prison decks or stax were very popular in legacy and vintage days because of winter orb and stax that players would use and find ways of getting around them such as removing their upkeep ect. The format lost heat as modern started to phase out this style of play over the years. Although it is impossible to recreate the style in the same magnitude, I think I did an adequate job of making one that can work with the materials given to us.
Use Khans with Monastery Siege when dealing with decks with little removal or little burn such as green decks or blue decks. Then you should use the discard form the enchantment to use in conjunction with the Locket of Yesterdays to get around a little bit of the price of your own prison. Use Dragons if the opponent has chosen to Lightning Bolt your prisons.
If you feel you are getting mana screwed for whatever reason then you should use the Expedition map to retrieve an academy ruins and use its ability to retrieve expedition map as many times as you please. This also has good synergy with the Khans option of Monastery Siege. because you get your Expedition map back in adition to another card that you can discard to later retrieve with Academy Ruins.
When you are not playing against a fast deck like red or black ones you should sideboard out Trinisphere and replace it for a Platinum Angel or a defense grid. When dealing with a swarm deck you should sideboard in Reverence. (Although swarm decks already have a hard time against this deck because of Ghostly Prison and Sphere of Safety which DO stack if you were wondering.)
Most of the time you would be using the council of the absolute to lower the cost of some of your game winners like Tezzeret or lodestone golem, but when necessary you can use it to make sure some decks dont use remand or cryptic command or even a surgical extraction because if an opponent gets to use those cards it can be a setback to you.
Suggestions gladly accepted because this deck is still very much in progress!
