I use it all the time! I have two cards that only cost 1 mana: this one and the brownie. I will use them when I am building a team and have an extra mana left over. He will slow your enemy monsters and even if abilities are muted he still takes damage that would have otherwise been directed at another, more important monster in your team. Just have to be careful not to use this guy during battles where the speed stats are reversed. Thank you for doing these giveaways!
