Well we'll be seeing a lot of these in the upcoming YCS at kansas city. Rabbit Dino quickly became a force to be reckoned with in the OCG, but in the TCG, with cards like TGU and evolzar Dolkka ready to be added to the line-up, the deck will be all the more devastating. It will be curious to see how many will adopt the d-fissure variant that's so popular in the OCG. D-fissure is a strong weapon against the current top deck, plants, but rabbits have a very good matchup against plants, and d-fissure is a problematic weakness in a mirror match with a deck that isn't bogged down by the dead d-fissures. D-fissure can also slow the deck a tad, since it takes much longer to fill your grave for pot of avarice, a card much needed for this deck, since it runs out of rabbit plays otherwise. Its got easy access to three rabbits and can easily xyz leviair to squeeze another out, but without putting back its vanilla dino's, its only got two rabbit plays in it. with d-fissure out, only xyz materials make it to the grave, meaning not being able to succesfully xyz off your first two rabbits will make it very hard to get you to a third play.

I've instead opted for anothet tech that shuts down plants, and well most other decks. Grave of the super ancient organism. The only LV6 or higher monsters this deck plays are a pair of stardust dragons for starlight road, so it isn't bothered by the card at all. Currently i'm opting for :

Note that in the extra deck i'm currently running 4 OCG only monsters. I have no major tournaments this format, so no way am I investing in this deck. Rabbit is at 110 presale, I traded my tour guides when they were 200 a piece, and just those 6 pieces of cardboard would set me back 700 bucks, and still leave me without 3 Ulti Laggia and 2 Secret Dolkka for the extra deck, not to mention Zenmaines. Although Zenmaines i will invest in regardless.

The deck has been testing extremely solid so far. This deck strongly relies on Forbidden lance and Starlight road to stop the main outs to it. Rabbit in the meta will bring back Bottomless Trap hole, as it hits every important monster in this deck, and even two when rabbit uses its effect (also the reason starlight negates it, since it will then destroy two of your cards). Running those cards in turn allows you to run a decent backline, with besides the obligatory solemns, also the now obligatory BTH, and a pair of d-prison and a pair of grave (though some may still opt for d-fissure mained, or more tech like CED or the transmigration prophecy)

The principle plays are simple. Use Guaiba or rabbit to get two dinosaurs to the field, then xyz Laggia and Dolkka. 8 times out of 10 your principle play is Laggia as it can negate summons, as well as spells and traps and sports 100 more attack than its brother. Meanwhile dolkka comes out against empty backrows and when it just seems more logical to attempt him. Dolkka can not only use his effect twice, but twice in the same turn, making him deadly against hand effects like veiler, herald of orange and tragoedia. You negate an effect, if a player is stupid enough to chain herald, you can chain this effect again and it will essentially cost the opponent 3 cards for a swift -3. -2 with veiler instead.

When playing against rabbit you should be watching two things : keep their bodies off the field and get your field full of big bodies that can hold their own against their backrow, most notably Barkion and Stardust. I would even chance Thought Ruler archfiend in there. Problem is, once you have the big bodies there, they have nothing that can attack over it. So when they bring out Laggia its pointless, when they bring out dolkka they have to make you use your effects.

Starlight road being so effective means you need to be careful about activating storm, dark hole, torrential, mirror and bottomless if you don't have a solemn warning set. And meanwhile forbidden lance means you need to be aware they can strip your monsters of 800 attack to get over them.

Once it gets going the deck is very hard to stop. But if you get in before them, or they happen to draw dead which happens with cards like guaiba and vanilla monsters, you are in with a good shot.

Hope this was helpful to some. In any case, its a really fun deck, and on DN it doesn't cost a dime, so give it a whirl ;)
