The point here is that Buddyfight ACTs, so far, don't have activation costs, only payments made as part of an ability's resolution. Just read any ACT ability, and you'll see that everything is a part of the ability itself. Compare to the Cast Costs of spells and impacts, which have to be paid in order to even use the card.

Another difference between ACTs and spells is that ACTs have no activation requirements. Take Jackknife "Thunder Storm" and his "Thunder Raid" ability as an example. To destroy a monster, he has to be on the right or the left at the time of resolution, not when activation of "Thunder Raid" is declared. So, if your opponent plays a Counter card in response that somehow moves Jackknife "Thunder Storm" to the center area, when "Thunder Raid" resolves, you don't meet the conditions, so you can't pay 2 life and destroy an opponent's monster. It's the opposite of Gargantua Punisher, for instance, which only cares if both center areas are open at the time you cast it, but not during resolution.
