This is a deck I've been testing that focuses on more the behemoths and bricking less with them.
Your main starts are either Hidden City + Guru or Archer due to their ability to get a big boy to your hand or straight to the field.
A few wild support cards I found to be pretty hand is Burst Rebirth, Trap Trick, and Pot of Forbidden (PoF). Rebirth allows you send a behemoth or pot to the grave and get it back at 2k LP which is steep yes, but the amount of times I had this card face down to revive like Ultra, PoF, or Umaster flipped games for me. Trap trick allows to search almost all the traps in the deck. PoF is a strong flip card that can be sent by Glacier or Succession and revived with Rebirth is a good start to turns or stopping plays if your opponent doesn't plan for it, but it is a major brick in the hand.
