you cant without ar
Deoxys isn't in Platinum. Sorry to burst your bubble.
you cant
go to pal park
no. If you have a Pokemon gameboy game migrate deoxys onto platinum and go to pal park on rt 221 and find it in the grassland area.
Go the spring path and walk around until you find deoxys and use your poke radar if you can
you cant with out a game shark or mod or action replay
It's possible but you may not be able to catch a cresselia afterwards. Problem is, I haven't figured out how.
you cant get deoxys in platinum dumbnuts only emerald ruby sapphire so be smarter dumbnut!!!!!!!!!!!!!!!!('_')
you have to upload it through pal park from your leaf green or fire red. then catch it in pal park.
u can't catch it but if u need help just e-mail me. Michellepan2100@hotmail.com
1. Catch it in a Pokémon GBA title with an event and migrate it to Platinum. 2. Action Replay cheat code. 3. Trade.
You would need to use an Action Replay or transfer it from Pokemon Emerald, FireRed, or LeafGreen, for it is impossible to catch Deoxys in any location in Pokemon Diamond, Pearl, and Platinum.
