magic the gathering, LRR
I am watching LRR's stream where they play Dandân - a community made mtg variant which is one of the silliest things I have ever seen.
The 2 players share a deck of cards (instead of having their own deck).
The only card in the deck that can do damage is Dandân, a fish card from 1993 that isn't even very good.
And most of the rest of the cards are about manipulating the deck to try and draw Dandân before your opponent does.
