I'm inventing a new format called "Elder Millennial Highlander."

No card can cost more than the price of avocado toast.

No card with the word "house" or depicting a house can be included.

Anything else I'm missing?

@kilnfiendpotter No mana rocks or mana producing creatures. Ramping up to success is for previous generations.
@kilnfiendpotter I just want to say this is genius.
@kilnfiendpotter Nothing with the word "Work" on it (because "nobody wants to work anymore"). All cards must kill something ("Millennials are killing...").
@kilnfiendpotter At the end of each turn, destroy one basic land, if able, to pay your student loans.
@kilnfiendpotter all copies of Murder have to be altered to depict a Chili's or an Applebee's
@kilnfiendpotter at least one of the mana a card costs must be sacrificed instead of just tapped
@kilnfiendpotter Gold and Treasure tokens are immediately sacrificed and optional costs can't be paid, because who has money? At the beginning of each player's upkeep, a copy of Smallpox gets put on the stack, to simulate the slow erosion of progress.

@kilnfiendpotter Some minimum number of cards with upkeep costs.

You can ask your friends at the next table for help paying your upkeep costs.

@kilnfiendpotter All permanents have cumulative upkeep 1
@kilnfiendpotter Planeswalkers are verboten, as none of us can afford to travel.

@kilnfiendpotter When you attempt to cast a spell, roll a D6. On a 1, you must post to social media about the cast.

If the spell is successful, you must brag or seek praise, no matter how inconsequential the spell.

If the spell fizzles for whatever reason, you must tag your older relatives so that they may point out that they could have cast that successfully with ease, and you couldn't because you didn't try.
