yu gi oh deck obelisk Yu-Gi-Oh! - Egyptian God - the Tormentor making it a standout choice for both competitive decks and high Obelisk the Tormentor - Egyptian

Witch Enchanter and Boggart Trawler are shockingly my fav of the cycle, but I think almost all of them are very playable

Crush of Tentacles is the more easily playable Upheaval style effect and does see a lot of control and midrange play as you do not need to build around the card so much

So here's my take on what would a modern, fun and viable Kuriboh deck could look like

In non-duelist-related tech, the manga took place in 1996-98, and when KC's duel-tech wasn't involved had a standard 90s tech level, with VHS tapes and the occasional flip phone

is your best chance of finding something viable enough to run competitively, But if you want to use the best version of the deck, I wouldn't bother running these cards
