While being a good ranged fighter only, Aracha's lord skill can make Piercer teams obscene. Her own damage is hampered by her limited base attack, but with spider toxin and her AoE poison, she can still do some very nice things. She may not be the best fighter, but if you're running any Piercers she should probably be on your team.
