My advice to enjoy this game more.

I always play in Gauntlet mode but with challenge disabled. You pick a deck, and play game after game against different decks.
The decks you play against are in:
x:\Manalink\PlayDeck
I used to throw any decks I could find in there including tournament winning decks and stuff. But often some cards will crash the game or the AI doesn't understand how to use it. Or the deck works but it's too harsh and it beats you in a few turns. Or it's too weak and you beat it easily every time.
So I made several decks that I think are balanced and fun and put them in that folder. Now every time I do the Gauntlet I get to play against decks I know the AI understands and are fun for me to play against. I get fun matches most of the time now.
