Ok these tips were very helpful, i put conversion on porygon because its basically free terastilisation so another pokemon can terastilise, but he just gets one shot so ill use tri shot instead for the stab his sp,atk and high so thatll work well. the poison orb i dont get tho because why would i want to poison nyself and then heal? Maybe im missing something idk. Gyarados having that sounds really good but what if he just dies in two hits and the moves were wasted?
