Kadabra hits very hard even without a Life Orb and is often very nice for ending cleans by revenge killing something like Scarf Pinsir. Charge Beam is a viable option on Kadabra to make up for its lack of Life Orb, opting for a Focus Sash. It's only real issue is that Kadabra can never come in without a free switch and Probopass always handles it, making Grumpig the more consistent Psychic type in the tier.
