It's hard enough to breed for the IVs than to breed ivs + nature lol (I just hope no hindering nature)
Though I have Electabuzz, Flygon, Alakazam, Blaziken that can handle Tentacruel, while Blaziken can or should handle Vileplume/Exegg. Even though the chances my opponent will let me KO their Vileplume/Exegg with my Blaziken is low. I do see what you mean.
