Pretty confident anyone given the opportunity will choose to negate the effect.
Gates of the Underworld (SDGU-EN023)
 The Gates of Dark World
SPELL Field Spell Level ATK:
DEF: 		Pendulum
Scale:

Needs to pay the electric bill so people can actually see what they're doing.
Gates of the Underworld (SDGU-EN003)
 Ceruli, Guru of Dark World
DARK Fiend / Effect Level 1 ATK: 100
DEF: 300		 Pendulum
Scale:
If this card is discarded to the Graveyard by a card effect: Special Summon this card from the Graveyard to your opponent's side of the field in face-up Defense Position. When this card is Special Summoned by the effect of a "Dark World" card: Your opponent must discard 1 card.
(Super Rare)
Rating: 1 out of 5
The only "usefulness" from this is giving it to your opponent so you can discard 1 of your own Dark Worlds.
Gates of the Underworld (SDGU-EN002)
Snoww, Unlight of Dark World
DARK Fiend / Effect Level 4 ATK: 1700
DEF: 0		 Pendulum
Scale:
If this card is discarded to the Graveyard by a card effect: If it was discarded from your hand to your Graveyard by an opponent's card effect, you can target 1 monster in your opponent's Graveyard; add 1 "Dark World" card from your Deck to your hand, then Special Summon that target (if any) in face-up Defense Position.
(Super Rare)
Rating: 1 out of 5
They might as well be Zombies if they're going to love the Graveyard so much. At least they'd have better support.
Gates of the Underworld (SDGU-EN001)
Grapha, Dragon Lord of Dark World
DARK Fiend / Effect Level 8 ATK: 2700
DEF: 1800		 Pendulum
Scale:
You can Special Summon this card (from your Graveyard) by returning 1 face-up "Dark World" monster you control to the hand, except "Grapha, Dragon Lord of Dark World". If this card is discarded to the Graveyard by a card effect: Target 1 card your opponent controls; destroy that target, then, if this card was discarded from your hand to your Graveyard by an opponent's card effect, look at 1 random card in your opponent's hand, then, if it was a monster, you can Special Summon it to your side of the field.
(Ultra Rare)
Rating: 1 out of 5
The Deck's boss monster has multiple effects, but "quality over quantity" is a thing.
Machina Mayhem (SDMM-EN021)
 Machina Armored Unit
SPELL Continuous Spell Level ATK:
DEF: 		Pendulum
Scale:
Once per turn, when a Machine-Type monster is destroyed by battle and sent to your Graveyard, you can Special Summon 1 Machine-Type monster from your Deck that has the same Attribute and less ATK than the destroyed monster.
(Common)
Rating: 2 out of 5
The weaker the monster, the less it likely has to offer, but that's better than nothing.
Machina Mayhem (SDMM-EN020)
The Big Saturn
DARK Machine / Effect Level 8 ATK: 2800
DEF: 2200		 Pendulum
Scale:
This card cannot be Special Summoned from the hand or Deck. Once per turn, during your Main Phase, you can discard 1 card and pay 1000 Life Points to have this card gain 1000 ATK until the End Phase. When this card is destroyed and sent to the Graveyard by an opponent's card effect, both players take damage equal to this card's ATK.
(Common)
Rating: 1 out of 5
An unnecessary restriction for two payments and a temporary ATK boost. The last effect is even worse.

Rating: 1 out of 5
Same cost to attack as Dark Elf, which is Level 4 and has no other requirements anywhere.
Machina Mayhem (SDMM-EN008)
Machina Defender
EARTH Machine / Effect Level 4 ATK: 1200
DEF: 1800		 Pendulum
Scale:
FLIP: Add 1 "Commander Covington" from your Deck to your hand.
(Common)
Rating: 2 out of 5
1800 DEF is an okay defense, but nothing is achieved by getting the commander.
Machina Mayhem (SDMM-EN007)
Machina Sniper
EARTH Machine / Effect Level 4 ATK: 1800
DEF: 800		 Pendulum
Scale:
"Machina" monsters cannot be attacked, except "Machina Sniper".

Scale:
When this card is Normal Summoned while you control no monsters, you can Special Summon 1 "Machina" monster from your hand, except "Machina Soldier".

One of Andy's toy soldiers escaped from wherever in Andy's room it came from. It cannot possibly survive.

(A monster can only be equipped with 1 Union Monster at a time. If the equipped monster would be destroyed, destroy this card instead.)
(Super Rare)
Rating: 2 out of 5
Gearframe is pretty good, but this isn't all that useful as an Equip Card.
Machina Mayhem (SDMM-EN002)
Machina Gearframe
EARTH Machine / Union / Effect Level 4 ATK: 1800
DEF: 0		 Pendulum
Scale:
When this card is Normal Summoned, you can add 1 "Machina" monster, except "Machina Gearframe", from your Deck to your hand.

(A monster can only be equipped with 1 Union Monster at a time. If the equipped monster would be destroyed, destroy this card instead.)
(Super Rare)
Rating: 3 out of 5
Instant access to Fortress and has high ATK, but that DEF prevents a higher rating.

(Ultra Rare)
Rating: 3 out of 5
Other copies can prove useful and it has two effect to use. Could be stronger for its Level though.

DEF: 		Pendulum
Scale:
Send 1 card from the top of your Deck to the Graveyard. Add 1 Equip Spell Card from your Deck or Graveyard to your hand. You cannot Normal Summon or Set the turn you activate this effect.
(Common)
Rating: 2 out of 5
There's always the chance that the top card is THE Equip Card you want, but otherwise, this is okay.
Warriors' Strike (SDWS-EN017)
 Supervise
SPELL Equip Spell Level ATK:
DEF: 		Pendulum
Scale:
Equip only to a Gemini monster. It is treated as an Effect Monster, and gains its effect(s). When this face-up card on the field is sent to the Graveyard, select and Special Summon 1 Normal Monster from your Graveyard.
(Common)
Rating: 3 out of 5
Definitely recommend 3 copies for Gemini Decks as it's pretty much a key card.
Warriors' Strike (SDWS-EN004)
Gemini Soldier
WIND Warrior / Gemini / Effect Level 2 ATK: 500

(Common)
Rating: 2 out of 5
Searchable and can survivve 1 battle, but you probably won't get the effect off more than once per turn.

Doesn't do anything to really support the Deck's strategy at all.

This is what you need for a Gemini Deck, a strong, low-Level monster with a good effect.

Updated from Gearfried the Swordmaster and quite a bit better.
Marik (TCG) (SDMA-EN038)
Temple of the Kings
SPELL Continuous Spell Level ATK:
DEF: 		Pendulum

(Ultra Rare)
Rating: 1 out of 5
Too powerful to be even useful out of the box. Could've been a major selling point.
Marik (TCG) (SDMA-EN037)
Mystical Beast of Serket
EARTH Fairy / Effect Level 6 ATK: 2500
DEF: 2000		 Pendulum

Totally unusable outside casual Duels thanks to the banning of the next card.

(Common)
Rating: 2 out of 5
Easily put a Spell Counter on your field, but it's hardly going to be that useful. Most of them need more than that.
Spellcaster's Command (SDSC-EN019)
Magical Citadel of Endymion
SPELL Field Spell Level ATK:
DEF: 		Pendulum
Scale:
Each time a Spell Card is activated, place 1 Spell Counter on this card. Once per turn, you can remove any number of Spell Counters from this card to Special Summon a Spellcaster-Type monster from your hand or Graveyard whose Level is equal to the number of Spell Counters you removed.
(Common)
Rating: 2 out of 5
Rack up enough counters and you can bring out a pretty strong monster, but protecting itself is going to be tricky.
Spellcaster's Command (SDSC-EN005)
Summoner Monk
DARK Spellcaster / Effect Level 4 ATK: 800
DEF: 1600		 Pendulum
Scale:
This card cannot be Tributed. When this card is Normal or Flip Summoned, it is changed to Defense Position. Once per turn, you can discard 1 Spell Card to Special Summon 1 Level 4 monster from your Deck. It cannot attack this turn.
(Common)
Rating: 1 out of 5
Unlike Cursed Seal, the effect isn't really a worthy trade-off for any reason.
Spellcaster's Command (SDSC-EN003)
Defender, the Magical Knight
LIGHT Spellcaster / Effect Level 4 ATK: 1600
DEF: 2000		 Pendulum
Scale:

(Common)
Rating: 2 out of 5
Can even protect itself and has 2000 DEF, but only 1 Spell Counter can be on it at a time.

(Common)
Rating: 1 out of 5
So where's the real new cards for this Deck? These aren't what a Structure Deck should have.
Spellcaster's Command (SDSC-EN001)
Endymion, the Master Magician
DARK Spellcaster / Effect Level 7 ATK: 2700

(Ultra Rare)
Rating: 2 out of 5
Slightly stronger than Dark Magician, but the effects are quite bad.
