===Umbral Horror===
Vector uses an '''"[[Umbral Horror]]" Deck''' mostly focusing on [[Rank]] 2 and 4 [[Xyz Monster]]s. He utilizes monsters such as "[[Umbral Horror Ghoul (anime)|Umbral Horror Ghoul]]" and "[[Umbral Horror Ghost (anime)|Umbral Horror Ghost]]" to access his "[[Number]]s" quickly, while also using "[[Umbral Horror Will o' the Wisp (anime)|Umbral Horror Will o' the Wisp]]" to modulate [[Level]]s between them, along with "[[Umbral Horror Unform (anime)|Umbral Horror Unform]]" to summon other monsters while risking himself.

Vector uses several different strategies throughout his Duels. In his first Duel against [[Yuma Tsukumo|Yuma]] he combines "[[Magical Tomb]]" with "[[Number 66: Master Key Beetle (anime)|Number 66: Master Key Beetle]]" to lockdown his opponent, but this was actually a deliberate ploy meant to be countered by the "[[V (archetype)|V]]" cards he gave Yuma.

During his next Duel against Yuma, he focuses on [[mill]]ing his opponent's [[Main Deck|Deck]] through cards such as "[[Number 104: Masquerade (anime)|Number 104: Masquerade]]" and "[[Vain Betrayer (anime)|Vain Betrayer]]" since he knew Yuma would keep the "V" cards as their symbol of friendship. At the same time, the pre-set [[Field Spell Card]] "[[Sargasso the Different Dimension Battlefield (anime)|Sargasso the Different Dimension Battlefield]]" and "[[Sargasso Lighthouse (anime)|Sargasso Lighthouse]]" ensure his opponent suffers large amounts of [[effect damage]] while he remains unscathed.

After becoming the host for [[Don Thousand]], Vector utilizes the "Thousand" Spell Cards to constantly gaining Life Points from "[[Don Thousand's Throne (anime)|Don Thousand's Throne]]" which drains Nash's life force the more Life Points he gains, lockdown, and gaining an early advantage with "[[Contract with Don Thousand (anime)|Contract with Don Thousand]]" by forcing his opponent to pay 2000 points, and ensuring spells would be a backlash rather then as an aide, though "Contract" is mostly used for baiting Nash to use "[[Rank-Up-Magic - The Seventh One (anime)|Rank-Up-Magic - The Seventh One]]" so Vector can use the "Number C" monsters of his fellow Barian Emperors for a beat down strategy, and quick burn.

If the mentioned strategy fails he can use "[[Rank-Up-Magic Admiration of the Thousands (anime)|Rank-Up-Magic Admiration of the Thousands]]" to use multiple "Number C" monsters with the same rank to summon "[[Number C5: Chaos Chimera Dragon (anime)|Number C5: Chaos Chimera Dragon]]", a monster that gains great attack power, to locking down his opponents by removing key cards from their deck, and ensuring that they can't be used by placing them on top of their deck, to repeatedly using this effect as many times as he can.

His Decks, and strategy reflects his style to torturing, and feeling pleasure in tricking his opponents, and feed on their suffering taking pain to ensure he cannot be stopped.
