  We make a preliminary investigation into twisted $A_{2n}$ theories of class
S. Contrary to a common piece of folklore, we establish that theories of this
type realise a variety of models of Argyres-Douglas type while utilising only
regular punctures. We present an in-depth analysis of all twisted $A_2$ trinion
theories, analyse their interrelations via partial Higgsing, and discuss some
of their generalised S-dualities.
