I noticed this combo as i was reading the Smeargle card i had just got and it occered to me what a great combo this could be.
now Smeargle's attack(NEO discovery)says if yor opponent attacked last turn and Smeargle was in play then Smeagle copys that attck (minus discard energy and yaddadaddadd)i realised whoa this is broken the trick is .....CHANSEY!!!!!!!! Yep the big egg has a nother use (what is that now 57 or something?) here what happens you send out chansey your opponent attcks you retreat attach a DCE to smeargle and wham  and most of the time (in todays playing enviroment) you get a dead pokemon. This also is the ultimate ditto killer cause say ditto is out active against your Chansey he uses Double Edge he takes 80 from that then retreat him send out smeargle and hes dead.
Arcanine lovers tremble for this scenario arcanine Take Down that Chansey muwhahwhahahhaha retreat bring smeargle Dead RK9
Not even blaines RK9 can stop him hes practically un beatable
