Rio's Decks are titled "Static and Dynamic Boundary" (静と動の境界). They contain a number of LIGHT monsters, whose effects focus on preventing the opponent from using Spell Cards. He has 3 copies of "Royal Decree" to shut down their Traps and no other Traps, so "Royal Decree" has no negative effect on him.
