You can get this achievement by normally playing the game or you can boost it. First, you should make a deck that has a lot of "Burn" cards. These cards are cards that do damage to your opponent's lifepoints. I suggest that you have 3 Solar Flare Dragons and 3 Nightmare Wheels. Now, don't attack your opponent. Just let your Burn cards do the work.
As for the deck that your opponent should play with. Your opponent should have 3 Neo Spacian Air Hummingbirds in their deck. They should have lots of heal lifepoints cards.
You should get this well before 200 wins achievement.
