Note:
- I am the creator of this decklist, if you think you have seen an almost identical decklist with the same combo description earlier, it was my friend who uploaded it. They have since taken it down.
- I do think Utopia Lightning is a good inclusion for this deck because, from my experience, the deck has problems dealing with big beat sticks with protections like Dragoons.
This is a Springans deck that I have been cooking and optimizing for a while, it has a fairly consistent combo line and a good endboard. The deck mainly consists of the Springans engine, with a small Mathmech engine and three Therion "King" Regulus, as well as some generic staples. The general strategy for this deck is to do everything you can to get Great Sand Sea - Gold Golgonda on the field and any Springans card in your hand. The combo line is as below:
- Great Sand Sea - Gold Golgonda effect to dump a Springans card from hand to grave and summon Springans Merrymaker directly from extra deck
- Springans Merrymaker effect to send any Springans monster from deck to the graveyard.
- Use the effect of Springans monster in GY to attach itself to Springans Merrymaker
- Overlay Springans Merrymaker into Gigantic "Champion" Sargas , then use its effect to search Tally-ho! Springans or any Springans/Therion card you wanted if you already have Tally-ho! Springans
- Tally-ho! Springans effect to detach to material from Gigantic "Champion" Sargas and add a Springans monster from deck to hand, then summon the monster you added and the one in the grave
- Overlay the two Springans into Primathmech Alembertian and Search Mathmech Circular
- Mathmech Circular effect to send Mathmech Nabla from deck and summon itself
- Use Primathmech Alembertian effect to tribute itself and revive Mathmech Nabla , which triggers Mathmech Circular to add Super factorial
- Mathmech Nabla effect to tribute itself and special summon Mathmech Diameter from the deck.
- Overlay Mathmech Diameter and Mathmech Circular into Gagagaga Magician use its effect to revive Primathmech Alembertian
- Use Primathmech Alembertian and Gagagaga Magician to make Number F0: Utopic Future , then Number F0: Utopic Draco Future .
- Your end board will consist of a UFD for monster negate, a set Superfactorial with three Mathmechs names in the graveyard, and a Champion Sargas for additional destruction/bounce once you detach a material from any XYZ monster.
- With better hands, you can also end on Therion "King" Regulus and everything else. Besides your Springans cards, Champion Sargas can also search Regulus, so getting to Regulus is not so much of an issue.
