I knew Hidden Power is supposed to be calculated by IVs, but I wasn't sure what kind of IVs are needed for a certain hidden power. Timid works too since I was disregarding Attack and would give priority to Special Attack and Speed anyways. Also, even if you do get a Dream Radar one I can always use an ability capsule to change it to its regular ability. Since 5V doesn't work, can Special Attack and Speed only be 31 IV instead? I'm not sure what would be needed to get HP Ice.
