IMPORTANT: This site doesn't have the card "CXYZ CHAOS BARIAN HOPE DRAGON", make sure to add that manually as it's an important card for the deck.
Brand new Umbral Horror deck profile with the new supports.
Make sure to always "Gorgonic Umbral Horror" or "V Umbral Horror" with "Seventh Tachyon" or whatever the searcher it is, if you miss one of them in the hand, I also suggest to search for "Shining Umbral Horror" with "Gorgonic Umbral Horror" as you can fast summon it without going for the xyz.
The ideal combo its: normal "V", search for "Thousand Umbral Horror", discard it and add the field spell, search with the field spell for "Gorgonic", special it, search for "Shining", use "V" and "Gorgonic" for "Number 104: Masquerade Vain", effect "M. Vain" search for the counter trap, use "V" effect from the GY to rank up your xyz, make "Number C104: Umbral Horror Masquerade, use its effect for banish oppo's cards, then make "CXyz Chaos Barian Hope Dragon", when you xyz summon bring back "Thousand" from the GY and xyz for "Number 106: Giant Hand", set the trap and you are good to go.
