Sparring Ground of the Artifacts

[Progenitor]

 

Lore:

 

All "Artifact" monsters gain 500 ATK and DEF.  Once per turn, during your opponent's turn, you can destroy 1 Set Spell of Trap card in you Spell and Trap Zone.  If this card in your possession is destroyed by an opponent's card, inflict 500 points of damage to your opponent for each Spell of Trap card on the field.

 

Basically i was going for the standard structure of an artifact spell/trap:

• 
  
• General Boost to archetype
• 
  
• Increasing speed or boosts during opp's turn
• 
  
• Negative effect to opponent for destroying it.
• 
  

What are your thoughts?  Any way this could be better or different?

An Artifact toolbow lol Artifacts already have Gryphon Feather Duster and friends I mean how much more power do you need lol. This card is very very very powerful.

Artifact monsters you control can only activate their effects if destroyed during your opponent's turn, therefore you can't use Gryphon's Feather Duster (a normal spell) to use their effs.
 
That being said, Sparring Ground seems balanced and specific enough to be a good support for Artifacts. Not sure, but the burn effect might be a bit much since an Artifact player will most likely have more Spell/Trap Zones filled.
 
OCG Fix:

All "Artifact" monsters gain 500 ATK and DEF. Once per turn, during your opponent's turn: you can destroy 1 Set Spell of Trap card in your Spell and & Trap Card Zones. If this card in your possession is destroyed by an opponent's card: inflict 500 points of damage to your opponent for each Spell of and Trap Card on the field.
