People think that antifa is revolutionary not realizing that it ' s sole purpose is to defend bourgeois parliamentarianism against all of it ' s enemies . <| sep |> It ' s good to have the choice but if you choose not to combo the card you are playing River Krokolisk . It ' s not even a strict choose effect because very often you will have mana restrictions . Example you want to bounce an SI 7 Agent that you played last turn back to your hand to deal 2 damage again but you can ' t because playing a card to activate combo plus playing this 2 mana card won ' t leave enough mana to play SI 7 again . In short , being able to bounce a card or not is only better if you don ' t need its effect right now . Shadowstep is way better when you do .
