However, those factors -- elemental type & attack, rarity, and level -- are merely criteria that factor into your odds of getting a critical hit. You can occasionally win without a critical hit, but you can't lose if you get at least one critical hit.
Even if you pick the perfect fighter for the job and use the right type of attacks against an opponent of lower rarity and level, you can still lose. You're just highly LIKELY to win; not guaranteed. On the flip side, even the fighter who is least likely to win has a marginal chance of scoring a critical hit out of nowhere. LOL
The power system is simple: fire is strong against nature; nature is strong against earth; earth is strong against water; water is strong against fire. Reverse them for weaknesses: fire is weak against water, etc. It's usually better to use hybrids because you want to match or exceed the rarity of your opponent.
But when picking a fighter, don't just select one who has the attack type you need. Try to avoid one whose element/s has a weakness against your opponent's attacks. If the opponent scores only weak hits, your fighter may get a 4th attack!
If dumb luck and persistence is your approach, that's fine too. It will just take you longer with more attempts. Just enjoy yourself however you do it.
Look at it this way. My Ancient Sloth is now Level 10 and my Hydro Yak is evolving. But for all my precise strategy and haste, I now have no battles to fight. I've burned up all the excitement. Really not a good thing.
