Supreme Storm Deity - Thunder Max Dragon

I had an idea for an impromptu boss monster of the Storm Deity deck I've been working on;

Supreme Storm Deity - Thunder Max Dragon
Rank 5 Wind
Thunder/Xyz/Effect/3000/2500
3 Level 5 Thunder-Type Monsters
Once per turn: You can detach 2 Xyz Materials from this card; for every 3 of your opponent's banished cards, your opponent banishes cards from their hand or side of the field.  If 5 or more cards were banished by this effect, this card deals double battle damage during this turn's Battle Phase.

Since it's already been established that Storm Deity are a deck that destroys banishes your opponent's cards through the effects of its main deck monsters (and some of its extra deck monsters) then it only makes sense that all this would be leading towards a boss monster who has an effect based on your opponent's banished pile.  In addition to having non targeting field removal he also can potentially attack the hand if the opponent has no board to wipe which can make him devastating against decks that commit no cards to the board but still have a banish pile like Psy-Frames.  Lastly if he's able to banish alot of cards, he deals 2x damage during the battle phase which is a clean 6000 damage or more against an open board.

And yes he's basically a +3 if your opponent has played at least 1 Pot of Desires.
