Another easy one. I am safe to ignore but never used alone. I almost never reach the tower and even if I do, I don't do much. I am very effective in defending against P.E.K.K.A.and Mini P.E.K.K.A. if placed correctly and can completey shut down a lone musketeer or lone Wizard for a positive elixir trade.

What am I?
