I've discovered a very powerful Water tactic that requires Legendary ocean but doesn't use any of the cookie cutter Umi cards...

Level 5 big monsters.

If you have Legendary Ocean on the field, Giga Gagagigo is reduced to Level 4, meaning that you can instanmtly summon a 2650 ATK monster! Terrorking Salmon is also ideal, though is has 50 less ATK.

Edit: Sorry Giga has alreayd been suggested, but I would suggest puttign in Terrorking and similar monsters to maximise the effect.

Kind of common sense here....and old....problem is...high ATK isn't always the best thing because it wouldn't matter if Sakuretsu Armor, Trap Hole, Bottomless Trap Hole, Torrential Tribute, etc are sitting there...

If it hasn't been said by now. Hydrogeddon.

If it has been said. Hydrogeddon.

If you do not play him you shall be smacked with a wiffle bat.

So, again, Hydrogeddon.

EDIT: Let me reiterate what I wanted to say.

ALO with Hydro is just not optimizing him correctly. Umikari is much better. And let me say again. MUCH better. I don't run a water deck myself, I run a standardized Tomato Control with Hydros within it, and let me tell you they are just AMAZING. Double them with Pot of Avarice and you just have a swarm of water turtles.

True, losing two and drawing the third is sometimes a bad thing, but with a LOT of self-replacement monsters being run you will find Hydros eating them alive and swarming all three out.

Also, Hydros are VERY good tribute bait. Once successfully flooded onto the field all three are very hard to take down, usually one or two are thus Mobius or Blowback are right there next turn to pound away at the enemy forces.

So let me say it again.

Hy-dro-ged-don. NOW.

Oh, PS, Water Dragon sucks.

Not like he's NEEDED for every kind of Water Deck...he's just good....I don't use him in every water deck though...like my Water stall....

Half, you know Stall is obviously not something you'd run an Aggro deck-thinning swarmer like Hydro in :D It's like saying nothing can search for Hydrogeddon EXCEPT D. D. Capsule (which we all know can search for anything.)

I editted my first post.

Water Dragon does not suck either....I know this from using him first hand and he can be brutally hurtful to the opponent if used properly

Needing 4 cards to summon him though (three if you swarmed Hydro)? I'm sticking with my opinion of him. Kinda like Raviel in the other thread :D

The result is worth the work for me...meh...but then I do play OCG so of course I got other ways it making it work...

Cheater :(

From what I've seen I don't rightly like Water Dragon. Though, humorously, I was asked if I was running a Water Dragon deck when I showed my Hydros from my Tomato Control deck outright in one of the duels at last regionals.

Yeah...most little kids automatically assume I use Water Dragon when they see Hydrogeddon pop up in my Water Deck. Sometimes they're right....sometimes they're not...<< >>

Bring out Water Dragon...give it Scroll of Bewitchment...use DNA Transplant to make all f/u monster's Fire monster's and everything but itself will be dropped to 0..then after doing some damage...Raigeki Break it and attack with the Hydrogeddon's and Oxygeddon << >> XD

Wouldn't surgery override Scroll as it was activated second, like the Snatch Steal thingses?

Well, whichever order it works in...basically it hurts the opponent when used right

Yeah, though it seems a bit situational to me, are you using anything else that will support attribute changes?

Spiritual Fire Art and Spiritual Water Art together makes a fun deck too...since my mons will be 0 ATK from Transplant cept Dragon, I can at least use them for Fire Art and still do damage since it's original ATK

Ooooh, that's nice actually. Though a bit dependent on Transplant and Scroll (not as dependant as some I've seen though)
