Royal Paladins, one the first featured Clans next to Spike Brothers and Kagero and one of the more popular clans used. Used the most by Aichi Sendo, who has shown to be the only person currently with Alfred in his deck. The deck seems to have a variety of effects from boosting other units attack power (Starlight Unicorn) to even calling out other units from the deck (Barkcal, Liu) to even rearguard removal (Blaster Blade, Lohengrin).
The clan's races are varied just like their effects from dragons, elves, humans and even gnomes and other creatures. Currently this clan and the Kagero clan are the most supported out of the other clans, due to most likely the fact that the main character and his 'rival', Kai, use them exclusively.
The more commonly used strategy(before barcgal was ban from the VG circle) is to superior ride up to Blaster Blade, setting up the at least 3 rear guard, and having a Soul Saver Dragon in your hand, then riding soul savior over blaster blade by your third turn to instantly make use of it's effect. This combo though relies heavily on units like Flogal/Llew, Pongal(To search out the soul savior dragon) and Barcgal (to call llew/flogal) and that you were to have a dragon in your hand either before or on your third turn.
Weak to Kagero due to their rearguard retiring skills, retiring the barcgal/Llew combo, and also ruining attempts at a full powered king of knights Alfred.
it should be noted that royal paladins has many of their units involve calling selective reinforcement from the deck and many of their key cards are:
