6th Gen Krookodile VS Heliolisk

So, I have a pokémon X team but I'm debating on whether to use Heliolisk or Krookodile. My team is going to be:

Greninja
Venusaur
Aegislash
Sylveon
Noivern

Should I use Krookodile or Heliolisk for my 6th?

Im no expert at this kind of stuff sorry! but maybe you should pair the stats and look at what you gotta do who You might face what pokemon might be essencal idk tho im not a fighting expert

I personally prefer Krookodile- it would feel like your team would do well with another Physical attacker. Also with Heliolisk you have a vulnerability of Ground types with 2 Pokemon.

my vote goes to heliolisk but that's just bc i think it's cooler and more fun to use. when i'm having trouble picking between pokemon i just go with whichever one i want to use most, nevermind the stats or type coverage. 4/6 of my heartgold team is weak to fighting but i'm just like you know what. who cares. XY isn't that hard anyway so shrug.
