The Junk Warrior one is amazing, therefore I love you.

Black Hole is...interesting. Very interesting.

[Alice Moonflowyr]

Heh, cool. 9/10.

[Agro]

I could troll and call these 'junk' but I'm not sure you'd answer. So...

Make twisted junk synchron bring out Level 3 fiends; please DEAR GOD LET US HAVE SOMETHING LIKE TOURGUIDE BACK.
I'm gonna actually have to look up Level 2 fiends if I actually want to know if this card is OPed or not, because at the moment all I can think of is Battle Fader and Steelswarm cards, neither of which are useful on the field to synch away with twisted junk.

for Monoxide please edit: 'If this card was [i]banished by this effect: during the ___ phase of your turn[/i]:...'

Twisted Junk should only be able to use its ability on the turn it was sent to the grave, and only if it was sent in a certain way (see Odin)

Black Hole's effect is strange because it means that you cannot summon it if you've already made a summon that turn (you see the problem with wording there?). I like how it's basically an unrestricted Armageddon Knight that can do more. Wait a sec, maybe that's too much.

Fallin star is unfair. It's almost and automatic win the second it hits the field, since the opponent cannot activate spells/traps to stop it after it hits the field. Then you gave it a piercing effect, an effect that lets it leave the field to escape cards like Smashing and Dark Hole, and gives you a way to defend yourself? On top of that, it's not that hard to get out considering the other synchros. WAY TO OPED.

Let's not forget Dark High-*shot*

Fader is a level 1. Synchron only Special Summons level 2s.

Its effect is idiotically specific to being with. I'm [i]PRETTY SURE[/i] its fine.

Black-Hole is basically a weird-ass Doomcalibur Knight, but reacts to the very first card that activates, and then doubles as a weird De-Fusion.

The hilarity is all of this could be said about Shooting Star.
But I'll humor you, and remove the piercing effect + tweak something else. Other then that, I'm leaving it the way it is.

Wow Arms. Good eye. I hadn't noticed that Twisted only special summoned Lv 2 monsters.

Make it level 2 or lower, and make it summon banished monsters, instead of hand or deck monsters

No.
If it Summons a specific level, I can get away with Summoning from the deck.
[i]Especially[/i] if the Tuner can only be used for 1 monster.

I see your point. Never mind what I said earlier about banished monsters

Theres quite a few ways you can get away with good effects. You just need to be a little specific on how they work.
Much like Tourguide.

Exactly.
You can be broken if your restrictive enough.
Rekindling is a fine example of this.

[Bringerofcake]

Why does evil!Formula have its Summon Conditions like that.

I'd like to see Imperial Iron Wall against Falling Star and evil!Formula.

Currently, the only really credible way to bring it out is through infernities. (only 3 fiend tuners: Infernity Avenger; Barrier Resonator; Supay)

Rather, why are the materials listed like F.G.D. rather than every other Synchro Material?

Because I thought it would be interesting if it was like that XX-Saber Gottoms guy, but one step further.
I'll change it to be more accurate if you want, though.

[Bringerofcake]

It's not that important, I was just wondering.

...
Now I want to do more for Ruka to have her be like O'Brien vs Judai.

[Toffee.]

Updated some stuff, because I started something cool.

[Toffee.]

Added more "evil" counterparts, and threw in another support card.

[Brinolovania]

Hedgie is...weird. But hilariously awesome.

Oh, and make moar Twisted Synchrons.
