I would love the Ditto , and maybe the Grimer . The Geodude was tricky . I chained Paras until I got a Damp one , taught him Grass KnotGiga DrainFalse SwipeSpore , stocked up on Hyper Potions , Full Restores , and Leppa Berries , and so brought my Pangoro with Entrainment . I chained up until I got to 60 , changing out primary Geodudes after every 10 . Then , at 60 , I let him call one in , killed the primary , and false swiped the new one . He brought in another one , and I waited them out until they had both used all of their self destructs . I put both to sleep , swapped to Pangoro , and used Entrainment . The first one had Galvanize , so I swapped back , killed the second one , put the Galvanize one back to sleep , and then captured it . So it was involved to say the least !
