Anyfin is certainly punishing to slower control decks
(specifically Control Priest, Control Warrior, and Handlock
variants) but it's no more punishing to them than say Control
Priest is to Control Warrior, or Renolock is to Patron. Anyfin
loses pretty consistently to many other popular archetypes,
and on top of that is somewhat inconsistent by its very nature.
If it doesn't cycle well, or cycles into too much cycle, it loses
pretty handily.
