Sentinels of the Multiverse is a great game which understands how to make co-op fun. However where SotM understands how card games work and makes decisions from there, The Cauldron understands how SotM works and adds to and improves the base formula. This set is worth a buy if you love Sentinels. Now let's talk about why Doc Havoc is a great hero
Finally, there's a doctor in the house! While characters like Tempest and Omnitron-X have some consistent healing (if you draw it), it nice to finally have a character that's dedicated to keeping everyone else alive! He has cards that heal everyone, heal a single person, cards that heal himself passively and even a card that increases the amount of healing everyone recieves (but I do mean everyone so be careful when you use it). On top of that he has cards that let players draw new cards and retrieve cards from the graveyard, and he can even let other players play on his turn. This guy is a team player!
One problem with healers in most games is when you choose to be one, you resign yourself to just healing while all your teammates get the glory of combat. Fortunately, Doc Havoc isn't having any of that! The Doc brings a ton of support from being one of the few base set heroes to have ongoing/enviroment destruction to preventing enemy cards from entering play. Heck, he can even bring the hurt when he needs to with throwing syringes or just getting into a fist fight with an enemy! To top it all off, the Doc has a card that lets him turn the damage he inflicts into healing instead! So you can deliberately hit your allies to give them some extra points
Most support characters in games tend to sit back and only step in to keep the other players going, but Doc Havoc likes to be on the battlefield alongside the other heroes. He won't be inflicting the same amount of damage the Lady of the Woods or Tango One is going to, but he still keeps up while keeping everyone else up too. To end this, I'm just going to quote one of his cards; "You're sure this man has no super powers?"
