@UnluckyLester I think it depends what else you have and what you enjoy also. I for one would pick Santa if I were you. He’s slow, I know, but he’s a pretty decent tank, he gives some awesome debuffs:that -44 defense just like Isarnia that is amazing on titans, events and well, anything and everything. The -34% attack helps a bunch also to keep the team alive.
Minions are always great to have, take for example ninja tower where your health score counts also, my heroes with minions really make a difference there.
But if your playstyle is just smash and grab, then go for Marjana.
Reuben is nice also, but even so I’d pick Santa before him.
