But I could claim all day that I came up with this myself, but that would be like being player 3 in this game of Dominion:
Turn 1:
P1: buys chapel
P2: buys chapel
P3: buys silver (with $3)
Turn 2: everybody buys silver
Turn 3: P3 buys chapel
P3 trashes all starting cards before P1 and P2 because of dumb luck, plays aggressive-trashing Chapel-BM strategy. Manages to hit a 3-way tie when everyone buys 4 provinces, but wins on tiebreaker even though his opponents were playing a more sound strategy.
"Oh no, I didn't just buy chapel because I saw you guys do it! I had this planned all along!"
