Arrows and whatever instant dmg spell should be useless against graveyard, it spawns a skeleton every 0.5s, the perfect counter is poison (1 elixir gain) or any troop that can 1shot skeletons (maybe archers could be fine)So if skarmy is the new card, that could be ANOTHER zap lure card, potentially you could have a deck with Sparky, Goblin barrel, minion horde and Skarmy.
Don't forget graveyard or whatever it's called is coming too. Arrows might be required once again.
