Innocence is the first casualty of war.

To Sacrifice The Innocent
Continuous Trap

Only activate this card by Tributing 1 face-up monster which you have controlled for at least 2 turns, and which has not declared an attack during any of those turns. Special Summon this card as an Effect Monster (Fiend-Type/DARK/Level 8/ATK 3000/DEF 2100). (This card is also still a Trap Card.) During each of the controller's End Phases: The controller takes damage equal to the ATK of the monster tributed to activate this card.

The weak, the innocent, and the children are nothing but liabilities, but do not consider them totally without redeeming merit. After all, there are certain entities who would trade you more... useful things in exchange for them.

Interesting concept ...

This card can make great combo with Pyro Clock of Destiny: After resolving that card you can use it during your opponent's turn, and it would be more better when using it on 0 ATK monster... However, I suggest to reduce its ATK a little bit...

I would give the option to Special Summon to either player's side of the field, making it a distant cousin of Lava Golem and pals.

A Pyro Clock Support-card? Sweet.

 

Add an effect so you can't tribute monsters with attack points that is below one thousand and you're set, I think.

Do you need to control the Tribute through two of your End Phases? Does the Tribute need to be face-up during both of those turns?

 

Can I Set a Spirit Reaper, let it flip face-up from an attack, and Tribute it the following turn?

 

If so, this card is relatively easy to set up and provides a lot of ATK, but the Trap Monster it brings out is terribly fragile.
