Utopic Vanguard

[Thomas★Zero 19]

Utopic Vanguard
lv 8 LIGHT
Warrior/Fusion/Effect
2 Level 4 monsters
Must be Fusion summoned. While on the field or in your GY, this card is treated as "Number 39: Utopia" When a monster attacks: you can banish 1 Level 4 monster from your GY; negate that attack. When this card leaves the field: you can Xyz Summon 1 "Number 39: Utopia" monster from your Extra Deck using 2 of your banished Level 4 monsters as Xyz Material. You can only activate this effect of "Utopic Vanguard" once per turn.
ATK/2500 DEF/2000

So Utopic Vanguard is a generic Fusion using Level 4 monsters that acts as a defensive card that blocks attacks by banishing Level 4 monsters from your graveyard, also when its destroyed it also can generate the original Utopia or Double (since I stated monster after the name for a that reason) from your Extra Deck using the banished Level 4 monsters as material to summon it.

Ideally this can work in any deck that uses Level 4's by just having a polymerization in the deck but also can work effectively in Utopia decks as this also helps set up your Utopia when this is destroyed for going into Utopia the Lighting. Lastly while this card can negate any attack including its own, it makes Double or Nothing a more effective card in the deck.
