Dungeon Maker: Deluxe!

From BoardGameGeek:

You and your fellow wizards have a bad habit of pilfering each other's dungeons. However, this time you're prepared! You've fortified your dungeon with a bestiary of nasty creatures. Imps. Dragons. Werewolves. Each with their own magical powers, ready to pounce. You leave them on guard as you depart for your own dungeon-crawl, only to discover: your fellow wizards have done the same. And they have a cave troll. The game has 3 stages: Fortify, Exchange, and Crawl. In the Fortify Stage, all players take each turn simultaneously, drafting 1 card to place defenders into their dungeon. In the Exchange Stage, players exchange dungeons. Each player shuffles their cards to form a personal draw pile. In the Crawl Stage, all players take each turn simultaneously, using 1 of their cards to clear defenders from their opponent's dungeon. The game ends for everyone when a player finishes clearing their opponent's dungeon. Win by scoring points for fully fortifying your lairs and clearing your opponent's lairs -- and by not running out of mana or vigor during the Crawl Stage. -description from the designers
