with conversion, but the prob without smeargle is it doesnt have spore. like if they is lets say a aracnine, and a vaporeon facing u, and u have smeargle and shedinja: u spore the arcanine and have shedinja use protect, and vaporeon uses surf and hits smeargle and arcanine is asleep and he cant use flamethrower on ur shedinja. if u used proygon2, then your shedinja is toast and you cant use mimic on conversion, unless u use t-wave and luck out the next turn by it being paralysed. its too easy for the first pokemon they send out to have a move that is either flying, ghost, fire, dark, or rock, so you have to be safe, and you can only gaurantee shedinja's survival if you stop the pokemon from attacking it. so u spore the pokemon going after shedinja, and have shdeinja use protect. then next turn they can only attack w/ 1 pokemon, and hopefully it cant use a strong move vs shedinja and since itll go after smeargle, smeargle's berry activates, u mimic it using conversion, and then u get conversion.
