Costs shouldn't be effects.
This is starting to bother me now. Third Hokage and Human Path both have costs that hurt your opponent. The Third hits chakra and puts -1/-1 coins on guys for a cost and Human takes cards out of the hand as a cost. That makes them unstoppable since you pay cost before you can respond. Both of these cards should be errata'd to have they're cost be pay 0. No cost for anything should be a neg to your opponent. Anyone agree?
