My formation
Abraham is core this can stun 3 units in his front. Beta as Tanker Magna just for buff she can be in front line because 3 units in her front hooked by Abraham this position can replace with R if enemy have Sarah (due to my R is weakest in team but can tank for awhile I use him as bait for make Sarah jump into Abraham hook, while she jump into this position R will jump off and make some damage before faint). Belle is sub stun she also can hook top unit to center. Sherry for damage she can take the rest unit that Abraham cannot take off, This position can replace with Kate for AoE damage or Inventor Eugene if meet jump unit they will jump to Beta instead.
