I FIXED SUBTERROR WITH CUSTOM SUPPORT! Yu-Gi-Oh!

[@dj3mNot-pho3nix]

This is my favorite deck too!! I play this deck all the time on master duel ranked!! Still off meta!! I love how they can Summon Thunder dragon Colossus as a boss monster with the Thunder Behemoth!

Subterror In The Hidden City: - When this card Is activated, once per turn: You can add or set 1 "Subterror" card from your Deck to your hand. - Your opponent cannot target face-down defense position monsters you control with card effects. - Monsters you control that were flipped face-up while this card was face-up on the field gain, 1500 ATK/DEF. - Once per turn, during each player's turn, you can activate 1 of these effects: Change 1 set "Subterror" monster on the field to face-up Attack or Defense position. Change 1 face-up "Subterror" monster on the field to face-down Defense position.

I feel like new subterror support could be really cool, especially with potential synergy with things like krawler or mimighoul

I think this support is awesome. I would also add 1 more card, so 4 cards in all. It could be an extender/recycle. It could ss itself face up or facedown by targeting 1 subterror monster in gy and add it back to hand. It could also ss a subterror from hand, deck, or GY, and finally, if another subterror would be destroyed by battle or card effect, you can flip it facedown instead. I think this would be ok. All hard OPT effects and certainly not broken by today's standards.

the krawler soma type off effects are what flip decks need, i think instead of a link one fusion, its better to have a fusion monster that needs a subterror behemoth plus a subterror that can summon itself like phantom of yubel, that has an effect like union controller, seach a spell/trap that metions flip. The spell card i think its to overloaded, it wil make the deck feel more sucky and thats awful for both the player playing the deck and for the player facing it

I have a few notes: 1. One element of the Subterror archetype is that all of the monsters are different types. You missed that part when you made Shaman a Spellcaster and Queen a Fiend, since they overlap types with Fiendess and Speleogeist. The Nemesis monsters are also all different levels, meaning the flavor was broken by making it Level 3 (the same Level as Archer). 2. I can understand these being rough drafts, but part of what makes a lot of custom cards unappealing to people besides their creator is when they lack proper capitalization and PSCT. No offense intended, but these are not the versions of these cards I would have demonstrated in a YT video. 3. You can actually go into Dueling Book and make the custom cards there. That way, you're able to demonstrate combos and such that would help viewers conceptualize your vision of what the deck looks like with these cards. 4. A bit minor, but as you mentioned, Tunneling definitely needs some type of restriction or it'll end up being a better Tearlaments starter than Reinoheart (though at the cost of a garnet).

One more thing I remembered: you mentioned that Fiendess isn't a card you want to see in your hand, but many other decks would love a quick effect omni-negate from hand that just requires a name of their archetype on the field. Some people play 3 Ryzeal Cross in Ryzeal which does even less than that. One of the keys to making quality support for this deck would be making Fiendess live before you reach a chokepoint and having the flip-down effect not compromise the quality of your endboard.

i dont know about the negate, maybe it should have a cost

[@madzygo9635]

Just play mini ghoul it's the only decent flip deck now

[@hiddenrapture6672]

why not put an errata for fiendess as well to say that she is always considered facedown while on the field, if ghostricks can link with a facedown why can a link count as a facedown. Also that fusion should probably have the effect to be able to flip herself facedown once per turn too. If giving them a fusion monster it would be cool to give them a searchable fusion that is a ritual spell or a quick-play spell (i.e. subterror Fusion) that can use any face-downs to count as a material (for a fusion monster that mentions flip monster in its text) or as the full cost for a ritual summon (for a ritual monster that mentions flip monster in its text) to make it generic flip support, for a cool flip pile. P.S. if that spell could also use FD monsters as the correct material for the link summon of a Krawler or monster that mentions Flip monster in its text
