This deck is a slightly modified version of MBT's
Tenyi Ten Minute Testing. Main point is over the combo is to get
Mare Mare in the GY to special summon it off of Shaman of the Tenyi's effect to go into a one card Tenyi Spirit - Sahasrara, So one of two boards you can go full combo is 1)
Shaman of the Tenyi,
Monk of the Tenyi,
Tenyi Spirit - Sahasrara, and
Vanity's Fiend or 2)
Shaman of the Tenyi,
Berserker of the Tenyi,
Draco Berserker of the Tenyi, and
Vanity's Fiend. Most of the time your board may just have
Shaman of the Tenyi,
Monk of the Tenyi, and
Tenyi Spirit - Sahasrara.
You also want to try and have all different attribute Tenyi Spirits in the GY because there graveyard banish effect is a hard once per turn. The ones to make sure you have over the combo are
Tenyi Spirit - Shthana,
Tenyi Spirit - Ashuna, and
Tenyi Spirit - Mapura.
The two main weak point of the deck is when
Shaman of the Tenyi activating its effect, it's a hard choke point to recover from if it's negated but if you have
Monk of the Tenyi on the field you can pivot into a
Berserker of the Tenyi and protect it with the level 4 Tenyi Spirits you have in the GY, also this deck has real protect against spells/traps, non targeting effects, and send/return effects.
