A couple of Subterror cards

[KH911]

I've been a huge fan of Subterrors ever since they released in Duel Links, and there are no words that can describe how disappointed I was to learn that their only extra deck monster is a Link monster, which completely shuts down Subterrors ability to summon from the hand. So I've decided to make a couple of extra deck Subterror monster that actually take advantage of face-down/flip monsters:

 

Subterror Necromancer

Level 12/Earth

Psychic/Synchro/Effect

1 Tuner + 1 non-tuner

1 Face-down monster you control can be treated as a tuner for this card's synchro summon. The following effects of "Subterror Necromancer" can each be used once per turn:

- FLIP: Special summon 1 monster from your opponent's GY to your side of the field

- Special summon 1 "Subterror Behemoth" monster from your GY, in face-down defense position, then flip this card face-down.

ATK/3000 DEF/2000

 

Subterror Behemoth Pileasus

Rank 10/Earth

Plant/Xyz/Effect

2 Earth Monsters

Face-down monsters you control can be treated as level 10 monsters for this card's Xyz summon. The following effects of "Subterror Behemoth Pileasus" can each be used once per turn:

- FLIP: You can detach 1 material from this card and target 1 "Subterror Behemoth" monster you control; that monster can attack directly this turn.

- If a face-down monster you control is targeted by a card effect: You can flip this card face-up or face-down; negate that effect, and if you do attach that card to this card as material.
