The first deck I used all the time was Alakazam/Xatu/Espeon. When I started played in tournaments, I made a weird Latios*/Shiftry DX/Jolteon d deck, but I was trying to build a better deck, that was an archetype. Problem was, I thought I knew about archetypes. I knew about Rocklock, LBS, Raindance, Mewtrick, Haymaker, and Mulligan Mewtwo. I ended up playing Mewtrick.
