An archetype of FIRE Thunder-types? Interesting; I would like to see their artworks. I'm thinking they would look like coils, engines and other mechanical parts on fire.

 

Basically they focus on ATK boosts and gaining card advantage mostly through battle, or by replacing themselves. With a few exceptions that I will address below, I can't spot anything wrong or broken in them so overall I think the archetype so far is good.

 

 

Thoughts on some of the cards:

 

Energy Vulcan Roaring Thunder:

Energy Vulcans don't look like an archetype that swarm much, so getting 3 of them on the field for the Summon of this card might be difficult. In my opinion, since Roaring Thunder doesn't have a broken effect (except the ATK boost that stack to become 3000 ATK), I think this card would still be fine if it required 2 materials instead. In that case, maybe you should remove the "If this card declares an attack, it gains 500 ATK." effect to prevent him from gaining too much ATK.

 

Dynamic Energy Cell:

"Then, the Opponent Draws 1 card."

I'm not liking that effect. Is it really that necessary? By itself, this card is a -1, and the opponent drawing a card just makes it worse. I know this card is intended to interact with the archetype to generate further pluses (Turbo Fire, Wild Coil), and the opponent drawing a card can help to balance the advantage, but I think you should be balancing those other cards rather than placing drawbacks on combo cards such as this one.

 

Turbo Fire:

Related to the previous point, I'm guessing this card is meant to be the main engine of Energy Vulcans, but drawing 3 cards is huge and might get out of control considering that Energy Vulcans are all about ATK boosts. I think you should drop the card drawing to 2 just to be safe, while removing the aforementioned effect of Dynamic Energy Cell.

 

Fuel Energy Cell:

Personally, I wouldn't mind if this was Quick-Play. 500 ATK is too low for a Normal Spell, and as Quick-Play you will be able to use it for surprise ATK boosts in Damage Steps during the opponent's turn, as you would do with Lance, Shrink, etc.

 

Blitz Crash:

I'm thinking this wouldn't be bad as a Trap Card, similar to Icarus Attack and Offerings of Snake Deity.

 

 

EDIT:

Actually, scratch the comment on Turbo Fire. After thinking about it, I don't think the card that much of a problem, considering that it has a restritiction, you must Tribute a beatstick that could inflict heavy damage on the opponent, and in essence it is just a +1 (-2 from the Tributed monster and the Spell itself, +3 from drawing).
