or point being??????? Salamance dies there as well....tossing around a play, that both the pokemon die in proves nothing at all. Also, you assuming an offensive spread on D-night. I presonally prefer a bulky one which allows easier setup, which btw, if I do run LO, mamo still can't oko.
mamo-adamant-choice band 252 attack, 252 speed vs d-night 252 hp. 252 defense- 81.9% max, which means, even with life orb damage I can live.
I deal 98% back, which means if I have rocks ups you lose mamo, this of course assumes you don't have rocks up, but considering you were speaking of LO breaking multi-scales this is safe beat me thinks. Also you forget, D-night doesn't have to run outrage :D do to being much much better at getting up more then 1 DD then salamance, he can afford to run D-claw, which means I can get away from your mamo!
