where do you get a electrizer, magmarizer, an a reaper cloth in pokemon pearl version?

Answer 1

Electrizer - you need fire red version in your gba slot. Elekids will be holding them. Low chance they are holding it.
Magmarizer - leaf green on gba slot. Look for magbys and it will be the same as elekid.
Reaper cloth - Turn back cave I think. I don't know the exact place because is a freaking maze.

Answer 2

Well, you can get the Electrizer on a wild Elekid, the same with a Magmarizer, which is on wild Magby's. The rate is not that high, but like said.

Magby, Stark Mountain, route 227, with LeafGreen inserted.
Elekid, Valley Windworks, route 204 (south), with FireRed inserted.

And you can get the Reaper Cloth in Turnback Cave, or on route 229.

Answer 3

well with the elec. make sure u have fire red in ur ds and go to valley windworks and run around. i found 3 elekids in a row all holding it so iono if only some hold it or all. same with the mag. it will b held by the magby but iono where to find it. iono netin bout the reaper cloth but if it like the others prob help by a pokemon, ghost type would b my guess.
