Sligh
The first Sligh deck was actually created in 1994 so you could say that this is one of the original decks. The name of the deck comes from the first player to have success with the deck, Paul Sligh, even though it was his friend Jay Schneider who built the deck and innovated the game.
Jay's innovation was to realize the importance of the mana curve, actually that concept didn't even exist before Sligh. The idea was that the deck should be able to use all of it's mana every turn in a efficient way so that it could kill the opponent before he or she was able to play all of his or hers expensive powerful cards. Therefore, the Sligh deck usually plays suboptimal cards just to get the curve mathematically correct.
In the 93/94 format the Sligh deck usually is mono red and contains all the good red aggressive cards like Lightning Bolt, Chain Lightning and Ball Lightning. The creatures in the deck may not be the best creatures in the format but they do their job. Classic choices are Goblin Baloon Brigade, Goblins of the Flarg, Ironclaw Orcs, Granite Gargoyle and sometimes Dragon Whelp.
