A Piece of an Archetype - "The Spark"

[JohnWalrusIII]

Hello all! In continuation of an archetype I've been working on, I have attempted creation of a type of "End Game." I would really like some input on this, since this is designed to be the final card to come into play. For help, the current method of Summoning the mentioned card "John White" is by banishing a card each from your field, grave, and both Decks.

[spoiler=The Spark - Absolution]

 

This card cannot be played unless you control "Pup'pet - John White, Keeper of the Spark" and 1 or more "The Spark -" cards. When this card is activated, card effects cannot be activated in response. This card is unaffected by other cards' effects. When this card is activated: Remove all Counters from the field and negate the effects of all other cards you control except "Pup'pet - John White, Keeper of the Spark," then banish those cards. While this card is face-up on the field: You cannot play other cards and cannot lose due to being unable to draw from our Deck. Also, the ATK and DEF of "Pup'pet - John White, Keeper of the Spark" become 4000 and it's effect becomes as follows: This card is unaffected the effects of other cards, except "The Spark - Absolution." After the damage step, if this card battled a monster: If no monsters were destroyed by the battle; This card can attack a second time directly. When this card is destroyed by battle: Banish 1 card from any place you control; Banish the card that destroyed this card and Special Summon this card to your side of the field. Each time this card deals damage to your opponent: Banish one card from any location you control. Also, your opponent can Special Summon one monster in the Graveyard or that is banished.[/spoiler]

if this is a card that goes with an set you made, then it should be posted with the set

It's hard to judge the card without seeing the rest of the set buuuut I can only see this being extremely over-powered or too slow to play in today's meta. I can't see much in-between.
