Of course you do, you just have to play smart and outplay your opponent.
In this battle the restrictions was poison and odd mana monsters with very small mana pool and as you can see i have not any attack power, just the warrior of peace and the divine healer with the tyeus paladium as a summoner. My opponent decided to end it quickly with full magic power which is good strategy (mostly in larger mana pool battles) but in the end i was the winner without even touching him!!
