This is pretty stupid:
I walked into this shop and saw some kids playing magic, so I waddled up, sat down, and watched. I sat there through five matches, and this kid keeps losing, even though he keeps changing decks that are "better" than the last. I'm thinking, this kid is a complete novice, so I open my pocket, and pull out my shadow deck that I keep on me all the time. I get the kid to use my deck, and I tell him that I'm only going to help him with the rules.
This kid gets out two 3/1 shadows, and two 2/1's on the first turn, next turn pumps them all to 5-6/2's, and attacks. Second turn kill.
