I generally just play unranked for fun usually with bullshit jank decks, so I quit pretty fast if I see certain cards come out. I.e. ashiok, big teferi and I have nothing to deal with it, bolas, if someone gets out two steamkin, etc. Less annoying to quit and find a game that won’t be so slow / or guaranteed to lose.
When I come across retards playing red / blue — I swear to god it’s always red / blue — playing slow as shit in unranked — sometimes I’ll quit, but sometimes I’ll drag out every turn as slow as possible if they start it first. Like bro, we’re not playing for money here, play your damn cards.
