 Pirahna army is great!
All you need is Pirahna army, Downgrade, Twin Swords of Flashing light- Tryce, Pathway to secret treasure, and triangle power.
(note- the pathway I'm speaking of allows any one monster on your side of the field with 1000 or lower atk to attack directly for one turn)
Pirahna Army = Water Lv 2 Fish/ Effect 800/200 The battle Damage this card inflicts by attacking your opponent's lifepoints dirrectly is doubled.
 
What you do is activate the pathway card, allowing it to attack dirrectly, then activate downgrade. That will put it to lvl. 0, or 1 since there is no lvl 0. Then, activate twin swords of flashing light-Tryce, then Triangle power. 12000 damage in one turn.
 
800 - 500= 300, then change it to 3000. 3000*2=6000, and with two attacks, 6000*2=12000!!!
