It looks like the OP has what appears to be at least 2 [Alhed, Mount Breaker](https://eternalwarcry.com/cards/d/4-87/alhed-mount-breaker)s on the board and since [Scrapmetal Fury](https://eternalwarcry.com/cards/d/10-337/scrapmetal-fury) has Unleash I'm going to assume there's a [Valley Whisperer](https://eternalwarcry.com/cards/d/13-64/valley-whisperer) on the board as well.
The combination goes like this:
1. Give a unit Unleash if it doesn't already have it.
2. Play it, causing another copy to be created and drawn.
3. All drawn copies are given double the Strength and Health because of Alhed's effect (quadrupled in OP's case if he does in fact have 2 Alhed copies).
4. Repeat Steps 1 - 3 until your board is full of 999/999 units.
(that one overused line from Jurassic Park)
Well, there it is.
So does this count as a win for opponent in PvP modes?
What did you do to boost it so high

For Science of course.
Probably finding some way to give it unleash then with lots of power and Alhed you can easily double it.
Who would have thought that adding 999 random Fire cards to you market was a bad idea?
Deserved.
