Because in the RP that I'm doing, Scrap Dragon is the 5th Signer Dragon

Scrap Homoncu

EARTH

Reptile/Effect

3/1200/1200

When this card is Normal Summoned: Target 1 "Scrap" Tuner in your Graveyard; Special Summon that target, but you can only Special Summon "Scrap" monsters this turn.

If you control a "Scrap" monster, during either player's turn: you can discard this card from your hand and target 1 monster on the field; negate that target's effects until the end of this turn.

 

Scrap Seeker

EARTH

Winged-Beast/Effect

1/100/100

If a “Scrap” monster (except “Scrap Seeker”) is Special Summoned from the Graveyard by the effect of a "Scrap" monster: Special Summon this card from your Graveyard, but it cannot be used for a Synchro or Xyz Summon, except to Summon a “Scrap” monster.

 

Scrap Bell

EARTH

Fairy/Tuner

1/0/0

If this face-up Defense Position card is targeted for an attack, destroy it at the end of the Battle Phase. If this card is destroyed by the effect of a "Scrap" card and sent to the Graveyard: you can target 1 "Scrap" monster in your Graveyard, except "Scrap Bell"; add that target to your hand.

During your turn: you can send this card from your hand to the Graveyard; “Scrap” monsters you currently control cannot be destroyed by other card effects this turn. During the End Phase of this turn, destroy all monsters affected by this effect.

 

Scrap Strap

Quick-Play Spell

Target 1 “Scrap” monster you control; If that target is destroyed and sent to the Graveyard this turn, you can send 2 “Scrap” monster from your deck to the Graveyard. You can only activate 1 "Scrap Strap" this turn.

 

Scrap Debris

Quick-Play Spell

If a “Scrap” monster is destroyed by a card effect: Target 1 “Scrap” monster in your Graveyard with a Level lower than the destroyed monster; Special Summon that target, but its effects are negated while on the field and it cannot attack this turn.

 

Scrap Shatter

Normal Trap (maybe quick-play spell?)

Target 1 “Scrap” monster you control; Destroy that target, and if you do, Special Summon a number of “Scrap Tokens” (EARTH/Machine-type/Level 1/ATK 0/DEF 0) equal to or less than the Level of the target. “Scrap Tokens” cannot be Tributed or used for a Synchro Summon, except to Summon a “Scrap” monster. You can only activate 1 “Scrap Shatter” per turn.

 

Scrap King

EARTH

Warrior/Synchro/Effect

6/2400/2300

1 Tuner + 1 or more non-Tuner monsters

If this card would be destroyed, you can destroy 1 “Scrap” monster instead. This card gains 300 ATK each time this happens. If this card in your possession is destroyed by an opponent’s card (either by battle or card effect) and sent to the Graveyard: Target 1 non-Synchro “Scrap” monster in your Graveyard; Special Summon that target.

 

Scrap Motor

EARTH

Machine/Synchro/Effect

5/2000/2000

More maybe

Seeker; Only really Searcher is capable of trigger in it, which is weird.
Bell says Goblin in the text. Derp.
Strap could be bumpped up to sending 2 monsters, because it's basiclly Storm but with a restriction, lacking the 'Draw 1' part, and slightly gimmicky.
Debris seems weird. Mostly because it negates the Summoned monster's effct.
King is interesting, because it also lets you use Worm with Chimera.
Motor, IMO, should have a slightly larger ATK boost.

Thinking of making it trigger when a Scrap is summoned by another Scrap, which lets it make Twin Dragon with Chimera/Beast

Fix'd

Sure.

Debris seems weird. Mostly because it negates the Summoned monster's effct.

It's partially meant to be used with Shark. And the rest don't care about effect negation all that much. To clarify, though, I did make it negate effects on field only.

King is interesting, because it also lets you use Worm with Chimera.

Partly why I made it like that

Motor, IMO, should have a slightly larger ATK boost.

Bumped to 700.

 

What about Shatter and Homoncu?

[Toffee.]

Homon and Shatter I liked, so I didn't really mention anything about them.
I mean, I didn't really see anything all that drastic about them and/or thinking too much about said RP in question.
Regardless, Homon is basically a smaller Chimera, so it gives you a little more variety in terms of what your going to play.

Bump maybe? It's still on page 1.
