So....what?

Today I didn't do too much. I decided to try this "Duel Monsters Genesis" online game to watch people play Yugioh. It's entertaining to say the least. Unfortunately, there are a LOT of people playing what they think are top tier decks, but because they don't know how to play or whatever else, they are doing crazy illegal or crazy bad plays.

For example, one player had Herald of Perfection with Royal Oppression. Now, Herald on the field with Oppression set sounds awesome right?

Well what happens if you don't have Herald and you had to use Oppression to stop a game winning maneuver from the opponent? Now your Herald is unplayable until you get heavy storm or Mystical space typhoon.

Card choice is very important in this game. A lot of people think that if they toss in some of the best cards in the current format, then their deck is now super-powered. Right now, a very powerful card is Thunderking Rai-Oh. While he is face-up on the field your opponent cant search their deck from card effects, nor can they special summon without the threat of it being negated. So why not run this in any deck?
Well, it's called synergy and random "tech", as people call it, can have very little synergy with your deck. If you are running Thunderkings, then your deck will have a lot of trouble if searching is very important to you. If special summoning is your win condition(such as in the Herald deck), running Oppressions may not be in your best interest. If you have a lot of valuable spell, trap, and monster cards that you can not retrieve from the graveyard, then Ryko, Lightsworn Hunter may not be the card for you.

"Tech", which is basically tossing in a card that may be outside your theme, or for the purpose of throwing off a specific opponent's play, is great when it's done properly. It's also something that can change your deck from playable to inconsistent.
