Deck chart

Deck types played by the top 8.

With the exclusion of TCG and OCG exclusive cards the overall event was favored by the OCG metagame, hence the dominance and win of "Inzektor" Decks, a widely played and a very effective Deck in the OCG. Initially Chaos Dragons Decks were played amongst many players during the event but without the TCG exclusive cards such as "Tour Guide From the Underworld" the Deck could not retain its fast paced capability as it does in the TCG.

During the top cut "Inzektor" Deck were played by every European player and every Japanese player, with the exception of Yohei Arimura, who used a "Skill Drain" Deck, which is effective against "Inzektor". Yohei Arimura's Deck utilized "Skill Drain", "Necrovalley" and "Dimensional Fissure", which can effectively damage the key engines of "Inzektor" Decks, by disabling "Inzektor Dragonfly" and "Inzektor Hornet" plays, as well as Summoning high ATK monsters, such as "Malefic Stardust Dragon" at ease.

A variation of an "Exodia" Deck was used by Jarel Winston. The Deck's main focus is to gain a lot of draw power by having the opponent have much more Life Points and draw "Exodia". The Deck utilized cards such as "Gift Card" to increase the opponent's Life Points, chainable cards, such as "Reckless Greed" and "Waboku", to use the Deck's key card "Hope for Escape". Winston also ran cards such as "Upstart Goblin" and "Twister" to increase the Life Point difference, as well as gain draw power and remove "Royal Decree". This strategy allowed Winston to draw 5 additional cards with "Hope for Escape" twice.
