I recently watched TCC's Shuffle Up and Play video where they play Pauper with Gavin Verhey, and at the end of it, he demonstrated the High Tide deck going off for 15 minutes.

As a blue player, I fell in love.

Unfortunately, no one else in my playgroup could be convinced to build Pauper just so I can fulfill my dream of boring them to death and winning the game by default, so I've been looking for something in Commander that has the same feel: a deck where the main win condition is a long, technical combo. I haven't had much luck finding one myself, as "durdly" isn't a search term on EDHREC or any other site, so I thought I might ask for y'all's recommendations! Give me your slow but inevitable wincons, your solitaire decks, your "Salt sum 88" stuff that your group only lets you play once a year on your birthday!

In the meantime, I'm gonna try to convince them to play Dandân.
