What defines a destabilizer

I have been looking at a thread about the distablizer class http://worldbeyblade.org/Thread-Destabilisers. I have heard, although I can't remember where, that 2 things make a stamina bey what it is. The first thing is it has to be able to maintain its spin. The second is that it deflects, destablizes, and lessens stamina of attacking/opposing beys, using the slopes on the stamina fusion wheel. What the destabilizer does is it takes the second part of what a stamina type bey does (deflects, destablizes, and lessens stamina of attacking/opposing beys, using the slopes on the stamina fusion wheel), and attacks opposing beys with it. To help conclude a question I have heard, a bey that destablizes, but have no aggresion, would by definition, be a stamina type bey. Would it???

Also, I have made a decently proficient destabilizer Beyblade. It is as follows-

Thermal Eagle LW105 HF

I know it could be improved. I came up with a list of ideas for top-tier destablizers on my introducing page- http://worldbeyblade.org/Thread-Destabilizer-Beyblader

I want to know what everybody thinks of this.
I think everyone knows what a destabilizer/destabilizing attacker is, and not all wheels have wheels.
