if you have dinosaur deck use them they are surprisingly useful, auto duel it up you dont need Destroyersaurus, Kabazauls itself is a MVP, just pair it up with e-con, security orbs, SRH, rising energy, metalmorph etc those will do as well
Dark Driceratops is amazing in it as well if you have it.
You made a good observation. I have been trying to get that card. I already have 2 copies of the card used to summon it but not Dark Paladin itself. BTW I cleared the floor.
I got lucky. I hopelessly played the floor with only 150 life points. Managed to beat it by activating effect of Hieratic Dragon to special summon BEWD, then tribute it to summon another dragon, then use dragon rebirth to special summon BEWD with full stats.
A guy had this deck (while watching PvP replay for 5 gems) where he uses sonic bird and Senju to add Dark Paladin in his hands, then special summon BEWD. Also had CV and SRH & sphere kuriboh in it. Though he lost with the same kind of deck but which was based on Red Eyes. That might have been because the player had first turn so he got the advantage.
