I've always liked Dark Gaia. I used to run a Turbo version of this deck that focused on dumping Valkyrion and Grinder Golem into the Graveyard and then summoning a massive double attacking, from Infernal Gainer, Dark Gaia with Dark Calling for the win. Reasoning and Monster Gate are long since limited so that version of the deck isn't nearly as consistent as it once was. I thought it would be interesting to combine the abilities of Doomcalibur Knight and Koa'ki Meiru Guardian into one deck to disrupt my opponent and then drop Dark Gaia with the game in hand. If I haven't won outright at that point I can also flip Royal Oppression to lock the field down.

The fact that I can also make Gorz into a double attacker seems like a great bonus to help clear the field.

The deck is just for fun right now, we'll see how well it tests out. I can't be the first person to have had this idea so it may not be all that competitive right now.

I like the Gainers, but I think you need more Targets to be able to use it properly.

You might be right, obviously it's not going to mesh well with Doomcalibur Knight so right now the best targets are Dark Gaia, Gorz the Emissary of Darkness, Tragoedia, Card Guard and Snipe Hunter. I was just about to put the deck together and start testing it so we'll see how it goes.

perhaps - 1 Infernal Gainer + 1 Neo Spacian Grand Mole?

or - Big Piece Golem + - Either Card Guard / Infernal Gainer + 2 Legendary Jujitsu Master?

otherwise interesting concept - better than the ones ive seen which use Fossil Tusker and co though another suggestion to use would be Mormiloth - good anti meta Rock tech to use - especially against swarm decks - Monarchs, Gadgets and even Glads..

Emm...you rely on Gorz too much? There's only 1 now!

Maybe Gold Sarco can help out.

oOops u already have 'em. Maybe Armageddon knights as well, can help with dumping, warriors themselves. Doomcalibur Tributes itself for ANY effect lolz, thats like -1 for a searcher getting sent to grave!
