Now, Moltres does admittedly have quite a few significant flaws, hence why I can't recommend it for higher than B+. It doesn't check many special attackers besides Volc, not wanting to go toe to toe with the Tapus, Pult or NP Hydreigon. While it can take a Knock Off well-enough and punish with Flame Body, it also doesn't like losing Boots for obvious reasons. It's not quite able to break other defensive mons besides Steels without SpA investment, so you need to partner Molt with a strong wallbreaker if you do use it. That said, I do think the positives it does bring to the table and its key advantageous match-ups are enough to qualify a solid anti-meta niche, hence B+/B rank.
