The basic idea of this deck is to get out your Tenyi Extra Deck monsters and other supports to disrupt your opponent (kinda) and have the biggest, baddest monsters. While certainly not Meta worthy, I hope it may be able to compete in that area, as I've put qite a lot of thought and research into this deck.
Basically, if you have the ability to, you want to get out Shaman of the Tenyi with Mare Mare in the grave so that you can get Sahasrara with Mare and a Mini-Mare. If you go second, you can get a Spirit Token, and therefore a Berserker by way of Linkuriboh, ending up with 2 monsters with 3000 ATK. Mystic Mine is in there to stall, and Cynet Storm is there, 'cause a) why not? and b) works with Set Rotation. Notice some cards can be bricks... hence the Side Deck. Note also that if you incorporate some of the Side Deck, you can get White Aura Bihumat (on your opponent's turn, no less). Here's how:
Step 1: Get Halqifibrax (should be easy enough)
Step 2: Use it's effect and get Jet Synchron and use to get Linkuriboh
Step 3: Summon Jet from the Grave, use Linkuriboh and Jet to get Dagda
Step 4: Use Dagda to set Scythe
Step 5: On opponent's turn, banish Halqifibrax for Wonder Magician
Step 6: Destroy Scythe using Wonder Magician's effect, then use Scythe and Wonder Magician to get Bihamut
Congradulations! Your mind has been broken (btw this was taken from a somewhat popular article by baMMax. Giving credit where it's due).
