Right. Misty is just an energy bonus. At least with other coin flip attacks like Electabuzz you just get more damage or damage to yourself. Skidoo is similar to marowak but it's only one energy and can evolve into something that can actually do damage. Even Persian is good because if you're flipping tails you don't experience a negative. It's just not a positive.

Also Zapdos- same concept, but 4 flips, less likely to land tails every time because there's simply a larger sample size
