Glaceon's only shot at doubles is with hail support and speed support. Tailwind/TWave/TRoom are all fine choices. Hailroom is among the weakest archetypes right now, I got a nice solution anyways. A fire type Pokemon that can redirect attacks is amazing for HailRoom, but the only fire type that fits the bill is Magmar. Follow Me Magmar/Trick Room Jellicent/M-Abomasnow/Glaceon form a good trick room mode. You may try adding a fast mode, full trick room is pretty hard to use in this meta.
Quiet Life Orb bulky Glaceon with Blizzard/Shadow Ball/Protect and something else is the way to go.
