Destroys your Monster Cards / Cannot be destroyed by card effects
Is clock tower prison even that great anymore in this game now? Cosmic cyclone can just banish it, and if it is banished and not destroyed, dreadmaster can't come out. And with how fast you can die in this game, will there even be enough time (no pun intended) for it to get going, especially after you lost one? Eternal dread and dread servant make it better, but idk now.
kind of a let down how there's only 3 monster and trap zones so dread master isn't going to be as strong as he could be
