borp's prototype mario card game heavily revised

you need:
- a [course deck] made up of 10 cards. no more than 1 copy of any course card allowed.
- a [draw deck] made up of 60 cards. no more than 3 copies of any card allowed.
- a way to keep track of point totals.

win condition:
- first player to score 20 points wins
- if you deck out (run out of cards in your deck), you're eliminated

setup:
- each player shuffles their course deck and puts it in the [course] area on the left.
- each player shuffles their draw deck and puts it on the [deck] area on the right.
- each player draws 7 cards from their draw deck for their starting [hand]. if you don't like your starting hand, you may [mulligan] once.
- decide the order the players will take their turns.

turn process
1. [draw phase]: draw 1 card from the draw deck (the first player in order does not do this on their first turn).
2. [untap phase]: untap all tapped cards.
3. [world map phase]: flip over the top card of your course deck and put in the [world map] area.
4. [main phase]: do any of the following in any order you want as many times as you want ↓
- <enter> a [partner] by tapping enough courses (or other cards that provide stars) to pay its <star> cost, then attach it to a course, yours _or_ another player's (it does not matter if the course is tapped).
- <exit> a partner by tapping it, then discarding it and any other cards attached to it.
- <move> a partner by tapping it, then attaching it and any other cards attached to it to a different course.
- <play> a [supporter] or [item] from your hand by paying its <star> cost. supporters go in the [home] area. items resolve immediately, then are discarded.
- <clear> a course by tapping 1 untapped partner at an untapped course. _you cannot do this if other players have untapped partners at that course_. when you clear a course, you gain points equal to that partner's [point value] and that course is now tapped.
- <battle> by declaring a battle at a course where both you and any other players have untapped partners (more on battling below).
5. [end phase]: end your turn when you have nothing else you'd like to do.

battling
1. tap 1 untapped partner. this is the [attacker].
2. choose another player's partner. this is the [defender].
3. the attacker deals damage equal to its [power] to the defender.
4. if the defender is dealt damage greater than or equal to its power, it's defeated and discarded along with any cards attached to it.
