Forum:How game-impacting is Cloak & Dagger?

I was just thinking about how much Cloak & Dagger can make a difference. I run a copy in my Side Deck, and when I use it against top decks like Tele-DAD, Zombies, and even in some cases, Lightsworn, it can really cripple them. For example, against Tele-DAD, I'll side in Cloak and Dagger and when I use it, I'll declare Malicious, which will really hurt Tele-DAD cuz Malicious is like the first step in a Tele-DAD strategy. With Zombies, I'll side in Cloak and declare something like Mezuki, Spirit Reaper, Plaguespreader, or Pyramid Turtle, depending on what the Duelist relies on more. When it comes to Lightsworn, however, it really depends on what the Duelist uses most often. If they use game-breakers like Celestia or JD, then I'll declare one of those. If they swarm with Wulfs, then I'll declare Wulf. The list goes on... I really think Cloak & Dagger is something that every anti-Meta deck user should be running. What do you guys think?
