Just got some pellets called "Claybreaker".
Does anyone know if it works?

I think that's just Gypsum, it's a lot cheaper to use that than the named
ready made granules if you can get it. However builders plaster is mainly
gypsum I understand.
Gypsum does break up clay for some years.

Where can I get gypsum?

From the plasterboards to be found in most skips. The rest is just paper and
will decompose.
