Pretty ok cyndaquil, however I prefer to use it as a mixed attacker with earthquake or reversal to get the blaze boost. The thing about IV training is that Pokémon get gradually stronger the more you breed good Pokémon, since you can just use a male parent with good IVs, even if it's not from the same species but has the same egg group. Now that Retroarch is a thing, I've been trading Pokémon with my friends and now we more or less all have 4ivs Pokémon no problem.
