As for more modern strats for Lanturn, try a max hp, even def and spdef ev spread, leftovers, stockpile, aqua ring, filler offensive stabs. Literally no-one is prepared for a 450ish (900ish in dynamax) hp titan of blubber. I never could figure out the best ability to place on the singles version of the set... But one water and one volt absorb while spamming surf and discharge in doubles seems like a laugh!
