By comparison with sangan you should change that.

I think your cards could be a bit more powerful although it looks like as you know how to balance.

I got just 1 suggestion. At the moment the stonger monsters support itself but i think it could be more interresting if the weaker monsters would support the stonger monsters.
For example:

|Black Thunder|Thunder/Effect|Dark|4|1700|0|
During your End Phase, you can send 2 Thunder-Type monsters from your Deck to the Graveyard.

Black Thunder|Thunder/Synchro/Effect|Dark|8||2300|2000|
1 Thunder-Type Tuner + 1 or more non-Tuner monsters
Once per turn, return 2 Thunder-Type monsters in your Graveyard to your Deck and destroy 1 card on the field.

Vrohi's first effect... any combo or something in mind? Cuz bouncing own monster seems pointless...

[byak]

You're making my cards bland... But I should make the synchros more powerful imo.

@Chillicano idk yet
You can bounce spells/traps too.

But we don't have many good Continuous Spell/Trap Cards for now. Maybe it'll have some abuse with Dark Treasury if we get some cards that benefit from RFPing...

wait idea

Oh, this will be nice

@Card 3:
"You can return 1 Thunder-Type monster in your Graveyard to your Deck to Special Summon this card from your Graveyard. "

Way too abusable as tribute/synchro fodder. It's just lucky that Thor's likely to be getting the banhammer or this'd be outright silly.

More Graveyard using cards seems a bit... eh. But still, the mentioned clause is the only really bit problem I can see.

And you never rated the cards I made for the NGD

>_<

anyway

First card ATK is way too high for a Level 8 Synchro I mean we have a level 9 Synchro that has less than that ATK and aa way worse effect...even when this is not a generic Synchro...
2600 would be just fine IDK

Second Card is ok actually thought a little Situational it can setup Graveyards easily...and may give you an extra card. With all of this the self protection effect may seem to be just an anoying Extra.

Vrondi is anoyingly Spammable

Rest is OK...IDK how a Deck build of this would look like ATM so I cant say anything else.
