So u should use all ur egg only arks, and wyrm fusions for ur team, I suggest these arks(not in this order per se):
Omegawyrm
Subzero tops
Typhon
Barricadus(if u are not in masters league)
Vegitiger(must have)
Shisaguard
Frillzeon(only if u can pair with two other good fire arks)
Shadowlance
Luxknight
Gremknight(good support ark)
Magmawyrm
Astroleon
Infernowyrm(paired with nilomoth for healing)
Pegasion
Don penguini(in the back, very tricky to use)
Megalorex(don’t need it but if u use it put in back)
Plasmorex if u want a heavy hitter.
Volcawolf(in front, preferably next to frillzeon)
Snowja
Of course u can’t use all of those arks, so u gotta find a strategy using certain ones, also get a Halopard because it’s haste and reinforce can be devastating
