do you/did you collect Yu-Hi-Oh cards?  

No i don't like

The Yu-Gi-Oh! Trading Card Game is a collectible card game based on Duel Monsters which appears as the main plot device in the popular Japanese manga Yu-Gi-Oh!, and the two Yu-Gi-Oh! anime series, which are Toei's Yu-Gi-Oh! series and NAS's Yu-Gi-Oh! series (known as Yu-Gi-Oh! Duel Monsters in Asia). In its fictional contexts, the game is sometimes referred to as Magic and Wizards or M&W in the original Japanese manga.

The card game is known as Yu-Gi-Oh! Duel Monsters: Official Card Game (sometimes shortened as "OCG") in Asian countries where Konami releases the game. The game is known as the Yu-Gi-Oh! Trading Card Game in countries where Upper Deck Entertainment distributes the game. It is inspired by the game in the manga and anime series; however the rules are adhered to more strictly and are comparatively more consistent and balanced than the game represented in its fictional contexts.

Each player is allotted a certain number of Life Points at the start of the game (8000), and the main objective of the game is to reduce an opponent's Life Points to zero, or win by alternate means. Like many other trading card games, Duel Monsters is a game mainly for two players to compete head-to-head, although there are unofficial variations of the rules thought up by fans that allow the play of three or more players.

There are also video games based on the card game, with minor differences between it and the collectible card game, and the video games generally give away copies of rare and/or powerful cards (usually three of them) with the game.

My son collects them but I have never bought them off of ebay for him. I just get them in the store.

I don't think Yu-Gi-Oh was around when I was a kid. However, my nephew collects the cards and will often make me play and I don't understand the stupid game. I don't think he quite fully understands it, either. I hate it, personally.

yeh i collected them and still do just for the fun of it

I got a lot of YU-GI-OH but they are only imitations.
Original packs contain 9 cards(8 common cards and 1 RARE)

which cost $3 per pack in our country.

Mine cost $.26 (15 pesos based on my calculations)per pack,

I buy many packs (almost 40-50)packs and some starter decks and enjoy playing it with my brother.

My brother even created a deck which consist of many banned cards and joined a local tournament that do not implement the rules about banned or restricted cards and allow semi-original cards.

The result my brother crushed the opposition many times and held as a champion for two months.Even if the other players try to copy his deck we bring a lot of decks I scout his next opponent and we device a plan and choose the right deck against his next adversary.

The winner of every tournament a $1 worth of stuffs from his store or 3 packs of cards.

I just want to share this after all yu-gi-oh is not a bad
collectible card game,rather very enjoyable and will test your imagination on deck construction.

First off, it is Yu-GiOh! not Yu-Hi-Oh (yes there's an exclamation mark there)...
Yes I do collect them, but then I'm a fan of all the card games and the board games invented so I collect everything I can get my hands on.
I also play with them... I guess you can say that I know almost all the card games' rules, and I can play with all of them.

yes i collected them i still own a lot of them but they only surve for amuzement when i'm bored :P
