I'm gonna start working on collecting info on their stats and maybe we discuss their optimal skills for each and think which one seem strongest:
These are the 3 "starters" using lvl 75 as the game auto sets your team to that lvl in the 23 trainer challenge and maxed out stars and Soul Boost, I will try to write what their setup could be, but please feel free to suggest a better setup:
Hopking: 245 hp, 222 atk, 172 def, 181 agi, Moisture Barrier (a generalist i guess?)
1. Illusive moves: 120 power water atk with 100 acc that boost spd, 4 turn CD
2. Zen Mind for +2 evasion, since Moisture Barrier gives the frog at least 1 free turn, 2 turn CD
3. Justice Strike 120 power light attack with 100 acc that boost own accuracy for Big wave, 5 turn CD
4. Big Wave 110 power water attack with 80 acc, it can alternate with Zen mind until the other two skill finished cooldown, 2 turn CD.
Ripfleshia: 285 hp, 172 atk, 205 def, 172 agi, Roots in the Earth (defensive mon)
1. Realm Shaker: basically 150 Power earth attack with 100 acc, 3 turn CD
2. Life Energy: heal 50% hp, since it's meant as a tank, 3 turn CD
3. Flower Storm: 55 power wind attack with 100 acc with 100% chance to reduce enemy Atk -1, makes it easier to tank, 2 turn CD
4. Needle Rose: 90 power 95 accuracy earth attack with 20% chance to Lacerate, a secondary STAB while Realm Shaker is in cooldown, 0 turn CD
(3 and 4 are easily repleceable: since the first two skills are basically used every 3 turns, we need a 3rd skill to fill every 3rd turn, but Ripfleshia doesn't seem to have that many standout moves
Falconix: 237 hp, 238 atk, 132 def, 238 Agi, Flame of Rebirth (seems like a class cannon with such low defense but has an extra life with the personality skill)
1. Blazing Passion: 120 Power 100 acc fire atk that boost own atk +1, a good way to finish off the 1st enemy, 4 turn CD
2. Great Fury: Raise own Atk +2, basically to set up a sweep, but be wary of anything that outspeeds or any enemies with priority moves, 2 turn CD
3. Heat Slash, 90 power 95 acc fire attack, something to start hitting enemies with, 2 turn CD
4. Flare Impact 140 power 90 acc Fire attack with 50% recoil, basically a last ditch attack, 4 turn CD
