VGC Moveset Help

Hey guys I recently bred a Bold Reuniclus (Life Orb) with 31/5/31/31/31/2 ivs and I noticed that my hidden power is ICE type.

According to Serebii/Metalkid this would give me a 68 base power ice attack. Now normally I should run Psychic/Shadowball but I would have to drop one in favor of HP Ice? Should I drop one and if so which one?

Damage Calcs HP Ice:
Landorus/Tornadus (HP-4, SPD-0) - 280-332 (100%)
Haxorus (HP-4 SPD-0) - 158-186 (100%)
Thunderus (HP-4 SPD-0) - 140-166 (100%)
Hydreigon (HP-4 SPD-0) - 124-148 (68.4% - 97.3%)
Sigilyph (HP-252 SPD -116) - 104-124 (58.1% - 69.2%)
Whimsicott - OHKO
Golurk (HP-252 SPD-0) - 2HKO
Druddigon - 2HKO
Archeops (HP-196 SPD-28) - 152-182 (82.6% - 98.9%)
Krookodile (HP-92 SPD-0) - 158-186 (88.7% - 104.4%)
Ferrothorn (HP-252 SPD-4) - 98-116 (53.8% - 63.7%)
Serperior (HP-252 SPD-0) - 118-140 (64.8% - 76.9%)

So basically I would lose my ability to hit Psychics/Ghosts for SE damage (Musharna, Beheeyem, Reuniclus, Jellicent, Chandelure and Cofagrigus). I do have a Volcarona on this team that could deal SE damage to all but Chandelure.

Comments or Suggestions are appreciated!

None of those things are particularly common, save Ferrothorn and the genies. You're not going to be keeping a Reuniclus in on Haxorus anyway. Psychic + Fighting is actually better coverage, and if you can't get HP Fighting you might want to try for Focus Blast.
