With Merlin and any Noble Arms or Gwen in hand, summon Merlin, activate his effect, summon Medraut. Equip Medraut with any Noble Arms. If you equipped him with Caliburn, activate Caliburn to get free LP. Activate Medraut, summon Borz, destroy the equipped Noble Arm. Once a Noble Arm was destroyed, activate its GY effect to bring it back from GY and equip to Borz. You can now activate Borz to reveal 3 Noble Arms card. Reveal Gwen, any random Noble Arm equip spell, and Until Noble Arms are Needed Again. Once a card is selected randomly by your opponent, you can either activate gwen (if the trap was selected) and equip her to Medraut, or you can equip a Noble Arms equip spell to Medraut. Now you can Xyz Summon Sacred Noble Knight of King Artorigus. Now use its effect on summon to bring back all Noble Arms from GY and equip it to him! Hahaha! You can end your turn (if your going first), or activate Artorigus, destroy a monster your opponent controls!
You can also use Sogen to boost the ATK and DEF of all your monsters, since they are all Warriors.
