Altmile is the Trial Deck for the Royal Paladin clan. It features 4 copies of the deck's trump card, Blue Sky Knight, Altmile. For this deck, besides having abilities that thrive in the face of adversity (active when all of the cards in the damage zone are face down), it also has the simple and strong strategy of calling units from the deck!

The cards with RRR foil treatment in each deck are Blue Sky Knight, Altmile; Absolute Blade Knight, Livarot; Lunar Crescent Knight, Felax; and one other random card from the deck (excluding Flash Shield, Iseult). The reissue cards included are 1 Flash Shield, Iseult (the ever-popular draw-trigger sentinel!); 3 Indestructible Knight, Earina; 4 Bringer of Good Luck, Epona; and 3 Flogal. You can strengthen this deck with Extra Booster 14 The Next Stage, available June 5.

This Trial Deck also features a new card type known as Orders! The player going second gets a Quick Shield when they ride on the First Vanguard. This pack includes 50 cards (16 different cards), a first guide, a play mat, 3 double-sided Gift Markers (Force I on the front and Force II on the back), and a Quick Shield card.
