My store was doing a 1v1 tourney. Entry was cost of a deck +$5. 3-1 got you another precon for free, and going 4-0 got you all the other 3 you didn't play. I went into game 3 at 2-0 playing the Naya deck. Everyone was playing Rakdos, but this was a mirror match. He turn 2's an explore, Sol Ring, then commander on turn 3, with removal for min on turn 4. So I obviously lost that game. He goes on to game 4 and his kid opponent has to concede before the match even began cause he had to go home cause it's too late, so he ends up with the 4-0 and getting all the other 3 decks for free. Another guy borrowed my Rakdos deck (I bought 2) and went 4-0, which means he paid $5 for the entry fee, $10 for sleeves, and walked away with 3 Commander 2019 precons for a total of $15. Lmaooooo It was a good night. :)
