No one shall ever know the truth behindThat fateful day. Artorigus went forthTo where the brilliant sword didst lay.'Twas the first of many feats so great,A legend through and through. We sing of him,Artorigus, the Noble and the brave.-From the Tales of the Noble Knights
Normal Summon Artorigus and then special summon Gawayn, then you can special summon Laundsallyn by sending Artorigus to the graveyard. Since your special summoned Gawayn would most likely be killed during your opponent’s turn, you can instead tribute him with Laundsallyn’s effect to search a Noble Arms card from your deck.
