I run a water deck but I dont see a use for 3xPenguin Soldier take out 1-2 and put in some more Amphibous Bugroth and Mermaid knight for direct and double attacks!

I just thought to run three, since Nobleman is down to one...

Anyone else?

Test out a Salvage in place of the Terraforming. When I played a water deck I found that with three ALO's, Terraforming was often a dead draw. With Salvage you can get back your used up penguins. I see the return of Penguin Locking(I love doing that. It ticks off your opponent so much.)

Yes, I always wanted to play that, but never had the room. I'll try it out.

Anyone else?

-1 Penguin Soldier
+1 Amphibious Burgroth MK-3

I just think that running any less than two Burgroths is crazy.

Nice Deck
8.5/10

With WATER decks, I always liked to take the beatdown path, so my suggestions will be:

- 2 Mobius the Frost Monarch (still requires a tribute, sidedecking should be fine)
- 2x Penguin Soldier (the Nightmare Penguins should be enough)
- 1x Spirit Reaper (not a staple and no place in a WATER deck)
- 1x Magician of Faith (same)
- 1x D.D. Warrior Lady (same)
- 1x Last Will (won't have many targets left)

+ 1x Gigagagagigo
+ 2x Terrorking Salmon
+ 1x Amphibious Bugroth MK-3
+ 1x Mermaid Knight
+ 2x Abyss Soldier
+ 1x Leviadragon Daedalus

These fixes make the deck more aggressive, your beatsticks should be dominating the field easily.

I've also played the beatdown version until not too long ago.

I find that the control version is more effective, but the beatdown version is fun with all of the normal monsters, just play Heart Of The Underdog.
