Naw, Gerode has it right.
1. Draw a card.
2. Put it into play.
3. Activate your 'Legends Of The Five Rings' Step (turn all cards sideways and shout Banzaiii!)
4. Repeat from 1.
Easiest way to win, simoply. Play monsters - plenty of small guys at 2cc and a few fat guys furrther up, and then plenty of removal spells or burn spells. If all your cards are either creatures, removal, or direct damage, then your deck is going to be solid in a very basic way.
The art of winning is very complicated - the true answer to your question is that the best way to win is to find out what the best deck is at the moment, and then learn how to play it perfectly. But for starters play monsters and kill your opponent`s monsters.
