started white 2 challenge mode. had a decent chance at riolu in flocessy ranch because of dupes clause, but actually encountered one first try. edged it up to 15 so it could learn force palm after taking out cheren's patrat, from there it was cake. solid IVs and nature on oshwatt is also a nice plus.
>>47665036nah, but you could do champs clause so any pokemon that you beat the e4 with you can't use again.
