What do you think about this?

Since I started here in splinterlands, I have been using the magic properties of all summoners in including the neutrals. One thing that caught my attention is that there were two magical creatures that have been bothering me as to their advantages and disadvantages. I am referring to the water splinter Ice Pixie and the neutral enchanted Pixie. If compared, the two have the same Health and the same Magic Damage. But I noticed that the Enchanted Pixie that consumes 3 mana has a slower speed compared to the Ice Pixie. This seemed to be disadvantageous to the Enchanted Pixie.

Please comment on these, I may be at a loss at this observation. Thank You!
