Forum:Skill Drain Waririor

A friend has a Warrior Synchro deck based around Skill Drain (anti-meta) and Immortal Bushi (Synchro Material). He carries plenty of copies of Exiled Force and traps to war off opponents, while trying to summon Goyo Guardian, Gaia (has 2-3 copies o), and Colossal Fighter. Any tips for him on how to improve it? This deck is more annoying than one would think.
