Whats really cool though, is that you can tap them to sacrifice X clues and, Target opponent reveals the top X cards of their library
Sometimes you need a specific Pokemon on your Bench, while other times you want to find an Evolution card to combo with your Rare Candy
Off the top of my head, in Standard and Modern, it prevents some or all of the use of the following cards: Every flashback card (in particular) Ancient Grudge Desperate Ravings Dread Return Dream Twist Faithless Looting Forbidden Alchemy Mystical Teachings Past in Flames Think Twice Unburial Rites Snapcaster Mage Narcomoeba Reanimate Exhume Every undying creature Every persist creature Gravecrawler Ichorid Ashen Ghoul Proclamation of Rebirth Polymorph Probably quite a few others 1) Drogskol Captain Hexproof is a very non-interactive creature mechanic, making it one of the more powerful mechanics to have been printed in recent years
The first card I jam is Basilisk Collar, so that Snapdaxs mutate trigger can kill anything, no matter how large
If you want it, nows the time
This card features the leader of Team Rocket, Giovanni, with his massive Mewtwo hovering over him
