My very first duel was in 2004 against some kid at school who I found out happened to have quite a collection of Yu-gi-Oh cards, almost identical to myself. I already brough my deck to school, and what was funny back then is that we sorta.. didn't play by the rules: Our decks were definately over 40 cards and were more like 100 and sometimes one of us would twist the rules just a little bit.
So yeah, my deck was actually very strong but so was his, plus the kid I was deuling had a bigger brother who was even better. So anyway, I decided to send out my Blue Eyes White Dragon, by sacraficing early in the game. He sent out his Red Eyes Black Dragon and basically I destroyed it but then on his trune he used Changed Of Heart to control me Dragon as use it against me, resulting in me losing more life points than him. By the way if you're wondering how many life points we used, it was 8000 because it was at lunchtime. So I was actually losing at this point when he mentioned something about a Yu-Gi-Oh club thing, which I found pretty wierd, but anway he also said that I had to beat him to be accepted into it and that there were 3 stages/ranks like the anime. Scyther Red, Obelisk Blue and Ra Yellow. I was intrested at that point and I dunno but it made me even more determined to beat this kid since he was so boastful.
So then, I decided to use my monster reborn and bring back my Blue Eyes White Dragon to the field and use it to attack his life points directly. Someone, I can't quite remember, further on in the battle he summoned Cyber headed dragon with three heads and attacked my Blue Eyes White Dragon but lucklily for me I used a trap card that negated it's attack and reverted it to 0 for that turn. Then on I just kept using my Ookazi's and my Blue Eyes White dragon to crush him, and put the upsmart back in his place.After that, a couple of weeks later I was the best out of the "club/group", I even bet the grade 5/6's of my school. Mind you, I was only in Grade 4.
Now, I hardly ever use them. They just sit in 5 shoes boxes doing nothing but gathering dust and making homes for who-knows what. :\ But occansionaly I get them out and sort them out and it brings back memories. And oh'boy by the time I left Primary School I had some very strong monsters and cards. The three egyptian gods and all of the Exodia parts. Not to mention what a kid called them "The three god's demons" and it's magic/spell card.
