However, his deck has an inherent weakness of not being able to superior call cards that can boost, so he improves it by including Techgal to compensate for it. He then improved his deck to focus on his new G unit, Aerial Divine Knight, Altmile. His deck is now focused on improving his formation and powering up rearguards with Altmile's skill.
Shion's deck changes again, focusing even more on cards with the Brave ability. He still follows his usual strategy of recruiting allies from the deck with cards like Holy Dragon, Brave Lancer Dragon and powering up his rear-guards as well as other cards to manipulate his hand to make Brave easier to activate. He will also usually start and end the game by rushing the opponent and calling the cards in his hand, making Brave easier to activate. This strategy is reinforced with his new avatar, Knight of Heavenly Decree, Altmile, making it easier to power up his rear guards without using counterblasts.
For his second fight against Valeos, his deck changes once more. He uses more units with the Brave ability with his new ace Higher Deity Knight, Altmile, which can call brave units from the deck. This means that he does not have to use the cards in his hand to rush the opponent so he could go on the defensive early game and offensive during late game. During his second fight with Valeos he gains a new G unit Immortal Holy Sword, Fides, which forces his opponent to guard with more than one card when his brave units are attacking, otherwise the attacks will hit regardless of their power coupled with the fact that Fides's second ability allows Shion to call three cards from the deck, increasing the number of attacks.
