Intern Elf Synergies: Melee units that do serious damage but have a slow fire rate such as Tarnished Battler, Brigand Battler, Hammer/Banhammer Battler, etc can help Intern Elf get kills and increase their survivability. (Do not pair Intern Elf with battlers that do too much damage or else Intern Elf won't get any kills. Mall Santa Synergies: Slightly more synergies than Intern Elf, can pair up with melee units with high damage and a slow fire rate, and can pair up with moderate/high damaging rangers that have slow fire rate such as Paintball/Sniper Battler, Baller Battler (if Baller doesn't knockback too many low health enemies to safety) Rocket/Crocket Battler (Crocket fitting in very well to severely weakening large crowds of mini tanks), Sheriff Battler (If enemy's dps isn't to high and can get it to critical health) and Conjuror can help Mall Santa summon hordes of kamikazes.
