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.
