Use King of the Swamp depending on what you need. You can send it to the Graveyard to get Polymerization or use it as a Fusion Substitue. It's recommended to have more copies of this card and replace other Fusion Substitute monsters.
The most broken, cancer and disgusting unfarmable 40 CPU ever. Look at what this son of a b.itch did: he had an Arm Dragon lv5 on the field against my weaker monster, while I had full LP (so no chance of ending the duel that turn), and his only Arm Dragon lv7 in hand. Instead of attacking to destroy my monster wanting to spec summon his lv7 (only to get a WoD in his face) HE DISCARDS IT for the cancer destruction effect. WHY. WHY THE HELL.
With Draw Sense, there's no need for extra Kidmodo's and the only cards Chazz has that can spell doom for your Blue-Eyes are Lightning Vortex and Megamorph, Lord of D. doesn't help against those and is too weak on its own to remain on the field.
The Dark Paladin deck is good, but it’s more useful if you can replace Dark Flare Knight with Buster Blader the Dragon Destroyer Swordsman. It’s stronger, and also gets the dragon boost that Dark Paladin gets, so you can potentially get Gravekeeper’s Vassal up to over 10000 attack with only one copy of Union Attack.
