Hey all. Let's see what we have to work with. >>>> Hey Satoshi, i haven't been playing Pokemon in a while, so i still have my old cards. I wanted to be different from everyone else, so i made a deck with a cool name! Leviathan! Woo hoo! I want it to be quick, but it's done pretty good so far. I just made it real quick with what i had. Please help improve my deck. Thanks! ~LeViAThAN~ -14 3 Gyarados 4 Lapras 3 Seadra 4 Horsea -25 2 Computer Search 3 Gust of Wind 3 Switch 3 Professor Oak 4 Bill 4 Energy Removal 3 Super Energy Removal 3 Rocket Sneak Attack -21 21 Water Energy >>>> Let's see...fairly good beginning, and a great name to match. But let's see if we can't make this monster of the deep a bit more terrifying. Um...the first thing I notice with the Pokémon is that you have no way to get Gyarados into play. I'm gonna give you the benefit of the doubt and assume that it was just a simple mistake and that you meant to add Magikarp in here someplace. =/ Anyway, Let's ditch the Horsea/Seadra line for 3 Magikarp, 2 Cleffa, and two more solid water type basics: Neo Genesis Wooper! This little guy is a great addition to any water deck. Let's move on for now, and see if we can't make the trainers a bit more stable. Ditch the Switch for two more Computer Search and an Itemfinder. Next, take out the Energy Removal for 3 more Itemfinder and a Recycle Energy to help with the kickback of the SERs. Let's also take out a Gust of Wind for a fourth Professor Oak. Finally, remove 6 Water Energy for 2 Lass, 3 Gold Berry, and a Nightly Garbage Run. This should make the deck run a lot smoother. The energy is fine. Don't touch it. All in all, this deck was pretty good to begin with. Aside from the missing Magikarp, you had a pretty good beginning-we've just sproused it up a bit. ;) Good luck and happy gaming!
