Countering Slow Start with Topsy-Turvy?

I’ve been thinking about how to deal with Slow Start, and I thought maybe I could use Topsy-Turvy and instead of Attack and Speed being lowered for 5 turns, they would be raised, but I’m not sure if it’ll work. So tell me, does Topsy-Turvy work if the stat change was caused by the Pokemon’s own ability?

No, this would not work.

Slow start doesn’t count as a stat lowering. (as in it doesn’t count as one of the stat changes caused by moves that lower or raise a stat by 6 stages) It doesn’t show the stat lowering animation when Regigigas comes out. It just halves the attack and speed stats, much like Huge Power, which boosts the attack, but it doesn’t count as one of the 6 stat change stages.

I hope I helped!

EDIT: the 6 stat change stages are:

For raising a stat, +1 (the first stage) is the stat multiplied by 1.5, +2 is multiplied by 2, +3 is by 2.5, +4 is by 3, +5 is by 3.5 and +6 is by 4.

For lowering a stat, exactly the same as above, except the stages have - before them, and they aredividedby 0.75, 0.5, 0.25 etc.
