Commander / EDH / Prison MTG Decks A prison deck functions by locking your opponent out of the ability to play in certain ways using cards and combinations to halt creatures activated abilities, ability to attack, the casting of spells, mana, etc in effect locking your opponent out of the game
Cards such as Tireless Provisioner and Academy Manufactor help to easily get you more tokens, and there are plenty of ways to get Treasure tokens as well to help ramp you into your powerful spells and permanents
Continue the subset of cards that don't care if you connect with an opponent, but rather look to any combat damage dealt, so these become super effective: Five-Alarm Fire, Holy Avenger, Sword of Hours, Lost Jitte, Tamiyo, Field Researcher, and the infamous Umezawa's Jitte
The main arguments for unbanning seem to be that there are other powerful ramp options available in the format and that Primeval Titan can be easily shut down with removal
I dove in to explore the optionsand boy, how wrong I was
Note that playing Jidoor from exile this way still counts as your land play for the turn, so you can do this only during your main phase and only if you haven't already played another land that turn
