"Subterror 2017/9/15 update" Deck 2017

Playing

Overseas precedent theme, Deck of Subterror. A deck that beats down using advanced and superlative large Flip Monsters.
VJ's new card was a relatively useful card, so I updated it a little.
《Subterror Guru》
4 stars / EARTH / Dragon / ATK 1600 / DEF 1800
1 and 2 each turn 1
①: Can be activated when this card is reversed. Add 1 "Subterror" card other than "Subterror Guru" from your Deck to your hand.
②: Can be activated by targeting 1 face-up monster on the field other than this card. Make that monster and this card a face-down Defense Position. If you have a "Subterror" card other than this card on your field, this effect can be activated during your opponent's turn.
The core of development and ad collecting is shambhala, decisive battle, and youma. Prioritize demons and decisive battles as a guru, and combine archers and warriors to develop his Subterror Maris. Since Guru's search is effective, I'll prioritize Shambhala and bring it to my hand. Terrafo is limited, so I'd like to use 《Metaverse》only for trays.
On the battlefield, he will add Spell Trap and Guru, who can change his battle position if Subterror Maris appears, every turn. Many of the effects are powerful, so it's easy to get the ad itself, but it requires some ingenuity to activate, so the key is how well you can use the effect before it's removed.
Rather than aiming for a long-term game, let's use the high RBI in the decisive battle to quickly reduce LP.

Strength

The main deck completes the fighting force, and the demon can play the dual role of deployment and obstruction. If the deployment goes well, the LP will have room to spare, so the God series counters should be fully loaded. One of the strengths is that even if the large size negates the effect, the deployment itself can be done by yourself or other support, so it won't stop functioning?
If the decisive battle comes, it is also good to be able to bring it into the short-term decisive battle with a high RBI.
If you have cards in your hand that can be shamballa or searched:
With shamballa activation, ef2 doushi search, doshi set, shamballa ef2 doushi table, doushi ef2 youma search, you can easily activate youma ef1, so it might be nice to have a thicker background.

Weakness

Only youma can deploy Subterror Maris immediately (the effect of 2 here and the search shambhala can be thoroughly countered).
Doushi solved my concerns about the hand side, but it's weak as a first move, so it's easy to get the board back with just that.
Due to the fact that the activation of the effect is reverse, without his Spells and Traps centered on Shambhala and the decisive battle, it tends to get stuck and loses the competition due to the ad difference.
Since there are no resistances, it is necessary to support him with his Spell Trap (quickly finish off with a high RBI).

Customize

In order to stably activate Shambhala, you can turn the tray, instead of Dust Force, there is no bottom, and as a defensive card, you can use Tsukisho.
If possible, change the format to a card that can be flipped from back to front.
As a monster, it would be nice to insert a card that is easy to SS at Lv7 or 10, which is the main monster, and connect it to the X Summon.
Voltinia can be Graiose, an RBI member combined with the decisive battle.
Since Lv4 has increased as a doushi, there will probably be a rank 4 center as well.
