This skill provides advantage to the deck that depends on Trap cards and effect damage although there are not many trap cards that could inflict effect damage in the current card pool.
When equipped with this skill, it is suggested that player includes “Attack and Receive” of 3 copies into the deck. As normally; without this skill, the activation of 3 copies would deal total damage of 3000 damage to the opponent’s Life Points. However, under the effect of Chain Trap skill, it would deal 3600 damage. If the opponent’s deck did not include any Life Points recovery cards, it would take 2 more activation of your trap cards to finish the duel. → Chain Reaction: deck recipe
Odion is the servant of the Ishtar family and has sworn his allegiance to Marik. An honest Duelist who Duels fair and square, his Deck is comprised of Trap Monsters, such as "Embodiment of Apophis," to ensnare his unsuspecting opponents.
The main idea is to avoid continuous trap, only fast traps that can be ativated in any fase also. Take a Legendary level 10 and put in your deck any kind of trap. Remember that you don't need to WIN the game, only use 10 Traps.
Not sure if you are aware yet, but i just got a new skill for odion from pegasus event (lv. 40 pegasus) - Trap Layer. I have included a screen shot for verification purposes.
