It's about time I showed this. Moltres can sweep teams somewhat like Yanmega can if you arent prepared for it. Agility is such a great stat-boosting move on Moltres and its one of the few things that seperates it from Charizard.
I used this set very effectively on both Suspect Test and Standard Ladder. It did work a bit better on ST but it works perfectly fine in standard and can give you the edge you need to take opponents down.

<p>Agility is Moltres' only stat boosting move but it can work wonders if used correctly. With a Modest Nature and 192 Speed EVs, Moltres will always outpace Timid Choice Scarf Gengar after one Agility.</p>
<p>Hidden Power Fighting is a nasty surprise for Pokemon such as Tyranitar and Heatran, both of whom are very common switch-ins to Moltres. Hidden Power Grass is also an option, being able to hit bulky Water-types such as Suicune and Swampert hard. Fire Blast is your general STAB attack, used to finish off most opponents. With Life Orb, and a beneficial nature, Fire Blast off a base 125 SAtk is no laughing matter. Air Slash is fairly effective against bulky Water-types as well as strong Dragon-types that may switch in on Moltres. If these Pokemon don't worry you as much as Stealth Rock and taking heavy damage does, Roost can be used to heal off any damage taken from Stealth Rock as well as giving you a reliable recovery move to abuse Pressure with.</p>
<p>Will-o-wisp is also an option if you want to take a more defensive approach on the set.</p>
