First I have a level 100 Aricuno-it knows Hail, Blizzard, Ice Beam and Fly
Next is a level 100 Moltres- it knows Solar Beam, Aerial Ace, Flamethrower, and Steel Wing
Then comes my level 100 Zapdos- it knows Rain Dance, Thunder, Roost, and Drill Peck
I have a level 100 Lugia- it knows Aeroblast, Hydro Pump, Extrasensory, and Sky Attack
After that is a level 100 Ho-Oh- it knows Fire Blast, Sacred Fire, Extrasensory, and Ancient Power
Then last I have a level 100 Groudon- it knows Fire Blast, Slash, Fissure, and Solar Beam.
Moltres: Switch Aerial Ace and Steel Wing for status or special moves.
Zapdos: Roost and Drill Peck are no-no's. And Thunder's accuracy is going to kill him. Go with Thunderbolt.
Articuno: Fairly decent but Fly should be replaced. Go with Nasty Plot.
Lugia: That Lugia is great with just one problem. Pulling off Sky Attack might become difficult. Keep it, but use turns where your opponent is likely to switch to use it.
Ho-Oh: Switch Fire Blast for Flamethrower and AncientPower for Sky Attack.
Groudon: Slash is the first thing that should go. Fissure should be replaced with Earthquake.
All in all, using the ideas I just gave you, your team would still have one glaring weakness. Electricity. A strong Electivire or especially a Zapdos is going to mow down your team. Still, with some changes it could be a good team.

I meant earthquake instead, I was looking at my sister's Groudon (oops). BTW Groudon is a ground type and it will cancel out electricity. It still knows Slash for its high critical hit ratio. Zapdos's Rain Dance enables Thunder to hit with 100 percent accuracy ( why would I have such a NORMALLY low hitting move? There's a method for my madness.) That's why I let Articuno have Blizzard with Hail and Moltres with Solarbeam and Sunny Day.(Hail and blizzard is a never miss, Solarbeam takes one turn to use when sunny, not two. Power hits FAST and ACCURATE) I have Articuno able to use fly so when an ELECTRIC type charges up, I can leave when the hi power hit takes place. And I forgot to say, Moltres I use for CONTESTS!!! It won th e mster rank in both beauty and cool. Articuno won the master for beauty, working on smart. ( I really do not like the move sky attack on a pokemon with such a low defence like Ho-Oh. It tried to learn it, but if I met up with an electric type pokemon while it was charging, I'd be screwed.) Thanks ALOT for the hints to fix my team!!!
