i can't trade groudon to xy. but I saw that kyogre can learn origin pulse in xy to but groudon not precipice blades. my groudon has learnt that move in oras. but if I groudon forget precipice blades can I trade it to xy without the red orb?
Yes, if you have Groudon forget Precipice Blades, you will be able to trade it over to X/Y, as long as it doesn't hold any of the ORAS Mega Stones or the Red and Blue Orbs
Also, Kyogre cannot learn Origin Pulse in X/Y.
