Forum:Gear Golem, megamorph

I was looking through card tips and it shows "You can also use "Cybernetic Magician" or "Unstable Evolution" to increase this monster's ATK to over 2000 and use "Megamorph", then use "Limiter Removal" for an OTK. "

For Gear Golem of the moving fortress, I dont play a lot so I was curious if someone could explain this to me. Megamorph increases the ORIGINAL attack by 2x, how would this be applied after limiter and unstable if the original is 800.

At that point it would be more realist to run unstable evolutions over megamorphs.
