Basically I always viewed destabilizers as a sub par stamina type Beyblade but with added attacking power. I've conducted a few tests to help this thread along.
MF Flame Cancer 100SF VS MF - H Earth (Second Mold) Bull GB145WB
10 - 0: Flame's win rate 100%
MF Flame Cancer 100SF VS Earth (First Mold) Bull 100SD
3- 7: Flame's win rate 30%
MF Flame Cancer 100SF VS Earth (First Mold) Bull 230WD
6 - 4: Flame's win rate 60%
*EDIT*
Flame Cancer does it job of defeating a defence type rather well as it should as it's a sub par stamina type but Flame Cancer fails against a pure stamina type. Though it must be said that Earth Bull 100SD was only defeating Flame Cancer by a small margin.
