Small-Time Heroes Cleric vs Nothing | Gamefound Preview Solo Playthrough

About Small-Time Heroes: Spirit & Spells, from BoardGameGeek:

In this cooperative deck builder, you'll take on the role of one of the Small-Time Heroes and work together to defend the town. With each battle, you'll build up your deck of cards, choosing from a variety of cards that represent your hero's unique abilities. As your power builds, you will defeat waves of minions and end with a final boss battle. Defeat the boss before they defeat you! In Spirit & Spells, you'll find two new heroes: the Cleric and Wizard. And four new bosses: the Puppeteer, the Slime Lord, the Nothing, and the Prince of Darkness. This is a standalone expansion that has everything you need to play the game or you can combine it with Small-Time Heroes: Sword and Shadow. -description from the publisher
