Silverfish overrides deckrules so it doesnt matter what you choose if your using silverfish. Silver.dll is plenty but it isnt perfect. you can edit the settings txt for silverfish to control, rush, or the experimental Mana option.
if you want to use more deckrules (again if silverfish external ai is active these are ignored) they can be placed in HearthRanger\DeckRuleSet
there arent alot of deckrules out there atm most people build there own and dont tend to share them but there is Yoins deckrules that he is always updating and i use it myself when i dont use silverfish
