it just makes it look like a pseudo impact

That's the point, it IS  a pseudo impact.

 However, there isn't any reason you can't just use the spell in the main phase right

 The impact great spell says it can only be used in final phase soooooooooooo

pointless to cast in the final phase

because it's a counter spell, I can use it in response to an impact if a time ever comes to do so. But I didnt feel like it being able to be casted during attack phase felt right.

Dark being able to fetch cards from the drop would need to be limited as to not  cause an infinite loop.

Light nullifying abilities could work

The slight issue with introducing new attributes to the mix, is that with every one comes another cantrip (and all the cantrips draw  a card,  even if dark brings back a spell from the drop zone besides itself without a draw as balance, it would still be able to get other cantrips)
