So this is a general Tenyi Deck, Using Genex Controller as the base normal monster, and proctoring the tenyi effects off of it so that you dont have to summon 2 Monks the same turn in the Tenyi Combo.
The Main Combo:
1. Summon Controller(Via Dai or Normal Summon)
2. Summon Tenyi 1
3. Link Into Monk
4. Summon Tenyi 2(If Ashuna was Tenyi 1, Make sure to use Ashuna GY ability after This summon)
5. Summon Shaman
6. Discard Card to summon Mare Mare(Get it to GY with Vessel, Foolish or Discard from Shaman)
7. Summon All 3 Tokens
8. Link Tokens and Mare into Sahasrara.
End Board: Shaman, Controller, Sahasrara.
If you expect a negate to appear on the board soon, make sure to get the Sahas tokens out sooner rather than later.
Extra Deck:
You shouldnt really be looking to summon Baxia, Yazi, or Triforce if you need to activate Shaman's Summoning effect.
Triforce is meant to be very late game, because summoning it off of a sahas token gets you the ability to resummon Baxia and Ashuna. Yazi, Baxia, and Ogre are you more common 2nd Turn Plays.
If I find that the controller is not a big enough Monster to protect itself, Sub it and Triforce out with Warwolf and Naturia Beast.
And if you're going second, most likely will sub out Called for Dark Ruler(If playing against Big Board Decks).
Definitely want feedback so post down below with thoughts and possible tweaks.
