These are the top ten cards I see played most in tourneys and friendly
duels:

10. Ruthus, the traveler:
Reason is because he came in the starter deck, so almost everyone has
him. Very solid monster!

9. King depthcon:
Several people I know carry him in their decks, even when they only
have a few water mana. He’s a good 6000 double breaker for only 7 mana.

8. Scarlet Sky terror
Solid Double breaker and power attacker with 6000 and for only 7
mana, very easily playable.

7. Explosive fighter ucarn
I have several of these so I guess I am the only one to use these
except for people I traded some too.  Solid double breaker with 9000
for only 5 mana cept. for the neg. effect, he’s almost unbeatable.

6. Death Blade Beetle
5 mana for a power attacker double breaker is pretty good, only
problem is he only has 3000 attack with out the 4000 power attack, but
for a double breaker he’s quite playable.

5. Zagaan, Knight of Darkness
6 mana+ 7000 attack+ Double breaker= Great Monster do I have too say
any more

4. Death Liger, Lion of Chaos
One of the best dark monsters,  7 mana for a 9000 attack double
breaker makes him highly playable in any darkness deck.

3. Urth, Purifying Elemental
6 mana for a 6000 double breaker is a great monster waiting to be played.

2. Hanusa, Radiance Elemental
7 mana with 9500 can destroy most any monster and a double breaker
makes him almost invincible.

1. Bolshack dragon
6 mana, double breaker, +1000 for every fire monster in your
graveyard, awesome Picture, Shobu’s favorite card, and a must in every
fire deck.
