This is a Party Box in the style of PleasantKenobi's. This is intended to support fast-paced, wacky games, where interesting things happen.
Any card can be played facedown as a land a la Lorcana's inkwell. Those lands have all basic land types, and can also tap for colorless. If one of these lands would be flickered, it returns to play face up if it's a permanent, and stays in exile if it's not.
This is a shared library for up to 4 players(can go beyond but honestly takes too long) and also features a shared graveyard. The library cannot be searched or shuffled. If a card instructs or allows you to place a card on the bottom of the library, exile it instead.
The list only changes through uses of Booster Tutor, which can grab a booster pack from any card game, not just Magic. I low key want a card in the party box from as many different games as you can possibly adapt to Magic's rule set, which is pretty flexible. I've got an ongoing document with unrefined rules text for each card from another game.
There are currently 4 jokers in the box, unlisted here. 2 for Magic, 1 for Pokemon, and 1 for Yu-Gi-Oh. These cards are easily recognized by the fact that they are just the card back from their respective game. They can represent any card from that game that has not already been played this session.
Life totals start at 20 to keep games brief. The growing number of creatures from other card games with hundreds or thousands of power help with this.
