Rock in Hydralander is a combo deck that revolves around using
Block Dragon with the Adamancipator monsters in order to build a powerful combo board, this version of the deck uses the advantage generated by these monsters to get
Barrier Statue of the Stormwinds by making
Simorgh Bird of Sovereignty, through
Reprodocus, and interruptions through
I:P Masquerena,
Apollousa Bow of the Goddess,
Borreload Savage Dragon, or
Abyss Dweller.
The main plays of the deck involve using any of the rank-4 engines the deck has in order to make
Gallant Granite, which can search Block Dragon or any other rock monster, using that and any other monster to make Reprodocus, then summoning Block Dragon to the Reprodocus zone, changing it to a Winged Beast and making Simorgh Bird of Sovreignty. Then Block Dragon's floating effect allows you to search for up to 3 rock monsters, generally the two level-2 Adamancipator monsters and Gigantes, these allow you to make anywhere from 1 to 3 additional end board pieces depending on the excavations of the level-2 Adamancipators and
Adamancipator Risen - Raptite.
