Subterror- Hidden City
When this card is activated: You can add 1 "Subterror" monster from your Deck to your hand. Once per turn: You can change 1 face-down Defense Position "Subterror" monster you control to face-up Attack or Defense Position. Once per turn, when an opponent's monster declares an attack: You can change 1 face-down Defense Position "Subterror" monster you control to face-up Attack or Defense Position, then you can negate the attack. You can only activate 1 "The Hidden City" per turn.
Changes: Made it into a subterror card so you can recycle it with Subterror Cave Clash.
Subterror Cave Clash
All "Subterror" monsters you control gain 300 ATK and DEF for each face-up "Subterror" and Set monster on the field. Once per turn, when a "Subterror" monster you control inflicts battle damage to your opponent: You can target 1 "Subterror" card in your Graveyard, except "Subterror Cave Clash"; add it to your hand.
Changes: Slightly lower the attack point gain but made it more flexible with face up "Subterror" mosters.
Subterror Behemoth Dragossuary

FLIP: You can activate this effect; this turn, Set monsters and "Subterror" cards you control cannot be destroyed by your opponent's card effects. You can only use this effect of "Subterror Behemoth Dragossuary" once per turn.
When a face-up monster you control is flipped face-down, if you control no face-up monsters: You can Special Summon this card from your hand in Defense Position. Once per turn: You can change this card to face-down Defense Position.
Changes: Made it so it protects Set monsters & Subterror monsters since alot of times your Subterror monsters will be face down.

Changes: Same as with Subterror Behemoth Dragossuary, made it protect both Set monsters & Subterror monsters.
