Good bot for pures

Hello sythe, I've never botted before so I need some help. I have a pure 50/67/25 (failed) with 85 magic and 72 range. What would be the best bot to obtain to train my pure and make cash? If it's perfect fighter where should I train. Also if I would want to make a new pure what bot should I use.

Thank you for your time,
