This deck just kinda works. If you're familiar with the new Earth Fairy monsters that are becoming meta, than you will quickly understand how this deck works. It's pretty powerful, it's a fun way to run Obelisk. This is not a great deck though, it is at best on par with the Face Card Knights deck that's used with Slifer/Ra. It's very easy to brick with this deck and become stuck, but it still works pretty well in my opinion.
I recently updated it to include some Slimes. Guardian Slime, Metal Reflect Slime and Egyptian God Slime. It makes the deck slightly more defensively consistent.
Alright, actual final edit I think. I added a few Lightsworn Monsters and side decked some Synchro Monsters as this deck can pretty easily summon lvl 8 Synchro monsters.
