Yanma is meant to evolve into Yanmega . At 390 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.

What is Yanma weak to?

In Emerald, watch for Aerodactyl (Rock), Arcanine (Fire), and Jolteon (Electric) when using Yanma. They all hit it super-effectively with STAB. Aerodactyl is the most dangerous since Rock moves deal 4x damage. Ice and Flying-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.

What is the best ability for Yanma?

Speed Boost is what you want on Yanma. Every competitive set worth running is built with that ability in mind. The alternatives (Compound Eyes, Frisk) work on paper but Speed Boost is what makes Yanma worth using.

What role does Yanma play in battle?

Base 95 Speed is workable. Faster than some, slower than many. On offense, Yanma is a physical attacker with base 65 Attack. Defensively? Fragile, can't afford to take many hits. Best used as a pivot.

For Emerald, you can run Yanma through the first few routes without issues. 390 BST won't carry you far though. Get it to Yanmega as fast as you can.
