The tricks usually involve things like surrounding the implosion core
with a neutron reflector which can reduce the critical mass by a factor
of two (from 11 kg to 5 kg or so for Pu).

For some reason I don't understand and haven't looked into, it's possible
to get a critical mass as low as 1 kg using plutonium nitrate solution
in a stainless steel implosion sphere. Yield would probably be a few kilotons.

Tritium is a yeild enhancer. Turns your A bomb into an H bomb.
