Based on Ben's Judge's Tower. I try not to make it impossible, just very hard.

All players share a deck.
All player's have their own graveyard.

You own every card you draw for purposes of things like Homeward Path.

Begin the game with 1 card in hand, +1 for each level of judge you have.

You must play every card in your hand as soon as legally possible. All optional modes are mandatory, to the extent that you can
fulfil them (ex. casting Mnemonic Wall with an empty graveyard is legal, but if there’s any spells in the yard you must target
one with Mnemonic Wall’s ETB trigger).

You must activate every activated ability of permanents you control once per turn per legal target as soon as legally possible.
Always activate abilities from the bottom of the card up (for instance, if you satisfy Mosswort Bridge’s hideaway requirement you
must activate it on upkeep, not the mana ability).

If a spell or ability has X in its mana cost, X is always 5.

You must attack with all legal attackers and block with all legal blockers whenever the option is presented to you.

If a player can activate the abilities of a permanent more than once per turn, that player only has to activate that ability once
each turn.

If a permanent has multiple activated abilities, activate those abilities from bottom up as printed on the card.

All players have infinite life.

All players have infinite mana.

You lose this round if you commit a game rules violation.

Play the game until there’s a winner, that winner gets a point, then exile all permanents, all cards in the graveyard, and all
cards in hands and start the next round. When the deck is empty, the player with the most points wins!
