Well don't know much about Jurrac you see, but by the BA we had, I see that was very possible to put aeolo on the field with another lv 4, so maybe a catastor would fit the extra, however, think about having things like Duality, Maxx "C" and Veiler, mainly maxx "C", because it could add some draw power to your deck, and also, extra consistency with duality and protection with veiler, I don't think any o these are REALLY necessary, but consistency is consistency, however, nice deck, a alternative way to use Laggia and Dolkka other than Dino Rabbits/Guide Rabbits etc.

BUT, Maybe you should think about not focusing too much on Dolkka and Laggia, in the end you could have stalled nicelly with Maestroke instead of Dolkka.

im curios wats hydrogendon doin in the deck

Hydrogedon apparently is to destroy a enemy monster, summon another hydro and then make a Laggia/Dolkka, I'd say, almost like Jurrac Guaiba in a Dino Rabbits deck, it only can summon himself, but if Dino Rabbits can use Jurrac Guaiba being the only jurrac on the deck, so why not.

Yea Okkiru you are correct. Hydroggen destroys a monster which ss another to xyz. Majority of the monsters are one card xyz's. Jurrac Guiaiba when it hits can fetch out ANY other Jurrac in the deck.
