With its ability to stop/prevent spell cards altogether, you can pressure your opponent even further by using Trap Jammer. This will help protect, not just Dark Paladin, but your other monsters from cards like Mirror Wall or other traps.
Dark Magician and Buster Blader uses different supports, and since it doesn't say that it needs those exact monsters as the fusion materials, you can use fusion substitute monsters instead. This will allow both of them to shine individually in their own decks, or make a fusion oriented deck by putting both Dark Paladin and Buster Blader, the Dragon Destroyer Swordsman.
You can use Outstanding Dog Marron or Sword of Deep-Seated so you can activate Dark Paladin's ability without losing a card.
Allows you to bring back your monster from your graveyard to your deck. This can be good if you have other cards to search for them again.
Allows Dark Paladin to attack multiple monsters in a turn and negate all their effect monster's effects.
Increases Dark Paladin's attack and prevents your opponent from being able to activate traps during battle phase.
