@mike-noble I was disappointed to see Weissman act this way. I wonder why he bothered to put that second COP:Red in play; if I were him, I would've been less obvious about how the deck I was playing was different from the submitted decklist.
I don’t think Crop Rotation was ever a legal 4-of before New Phyrexia. Card was pretty broken as a 1-of in shops and Storm before Misstep came around.
I played 5C Stax at 2009 Champs with 3 Crop Rotation. It was strong but not broken, finding the one-of utility lands that the deck ran without relying on the stronger tutors such as Demonic Tutor. I remember people being worried about it in 5C Stax specifically since that was the only deck running restricted Crop Rotation prior to the June 2009 unrestriction.
Some relevant tweets:
The situation in a nutshell: Athena posts a picture of Brian’s board position after losing to him with her red-based strategy. He notably has two Circle of Protection: Red in play. People realize that his submitted “decklist”/picture of what he was playing only contains one Circle of Protection: Red. Brian won the event, but as the tweet above details, he returned the trophy after this information came to light.
This is arguably a watershed moment for the Old School community and format.
