Horus Centur-Ion

I hope you liked fun, interactive and compelling back and forth, because this deck will definitely NOT do that! Sometimes anyway.

Centur-ion is a deck revolving around summoning level 12 synchro monsters! The downside is most of them need synchro tuners, multiple tuners, or specific named tuners. The upside is most of the best level 12 synchro's are completely generic!

The strong line this deck will do is normal summon Trudea, using its effect putting itself and Primera in the S/T zone, activate Primera to summon, us its effect to add Stand Up Centur-Ion!, activate it by sending anything from hand to grave, put Emeth VI in the S/T zone, activating Emeth VI and synchro summoning Legatia, drawing 1 card; finally, in the end phase, place Trudea in the S/T zone. This line will enable you to, in your opponents main phase, immediately activating Primera and Trudea in the S/T to summon them (making Trudea a level 8), then using Stand Up's 2nd effect to immediately synchro summon after getting a special summon to make Crimson Dragon. Then, use Crimson Dragon targeting Legatia to summon Hot Red Dragon Archfiend King Calamity and voila! your opponents turn is skipped giving you an easy otk turn 3!

The Horus card's allow for the easiest Zombie Vampire in the format, letting us mill 4 and praying we get lucky enough to grab any Centur-ion monster or another horus card! But they aren't just here to make Zombie Vampire either! Each Horus is also level 8, meaning them plus Primera makes any level 12 synchro! You also don't need to run as many Horus monsters either, just 3 Imsety and 1 Hapi are all that's required, I prefer the extra name as a just in case.

There are a ton of different ways to build this deck too! You can play pure, running desires, prosperity, bonfire, etc, you can play a bystial centric version, running Lubellion, Magnamhut, Druiswurm, Sarnoir and Branded Beast/Regained and also use them as level 8/6 cards to go into your 12s or 10s (part of the reason Chaos Angel and Baronne are in this list! Bystials in the side are the main enablers of them)

The funniest thing this deck can do is also hard summon ZEUS or TY-PHON because of how easily you can make 12 star synchros, meaning you can just make a calamity board going first and then, if you somehow can't get to an OTK, just summon ZEUS post battle! 

I should also note I'm extremely inexperienced with the deck, so please go and find other guides or watch other people play this deck to get a better handle on how to pilot this deck more adeptly Joshua Schmidt just uploaded a vid on his 2nd channel (link here) of him playing against Quantal on Lab while he played Centur-Ion, it's a great way to get an understanding on how to play this deck when you're on the backfoot constantly.
