...Keeping with this pattern, huh? Well...
......They look alike, The HP, Weakness, Resistance, and Retreat Cost are all the same o.0;. The attacks are even similar.
#1: Claw's too risky and Steel Wing's cost is too steep.
#2: Better first attack, and good second attack.
#3: ...First attack's the same thing as #2's, and the second attack is a bit stronger but a switcher instead of protection......
#4: The oddball of the group. 2 Energy for 20+ isn't too good comparatively and 50/50 50 (lol) is so-so.
Overall, I'd have to say that 2 & 3 are tied for first, then 4, and 1 in a distant last.
