Okay so I'm aware these are all Smogon sets because I'm new and trying to get the hang of competitive play. I grew up playing pokemon for fun with friends so I understand how the game works. That being said, I'm confused on the mechanics of Destiny Bond because sometimes when I use it, the opposing pokemon doesn't faint when I do. I've had pretty good luck with this team on pokemon-online.eu but I was debating on switching out Yveltal for Darkrai because I've had a lot of trouble with Dark void/substitute sets. I think it would be a great addition to my team but I like that Yveltal has a fire type coverage move and priority in sucker punch. The only other pokemon on my team that knows a fire type attack is groudon but his speed is lacking so I like having yveltal as an option for ferrothorn, mega scizor, etc. Thoughts or suggestions?
