Pokemon Trading Card Game Pocket is another that has a lot of waiting, specifically waiting for packs to recharge so you can open them
Unlike Hexproof, it just delayed interaction (rather than outright disabled it), and it could be answered by familiar cant be countered text rather than clunky, explicit text like Detection Towers
That is, they have the exact text as a previously printed card, but the name or creature type is different, usually for flavor reasons
One of the strongest Sultai cards, the biggest reason Muldrotha isnt a true cEDH commander is that it doesnt contribute much to most combos by itself and has a prohibitively high mana cost in that environment
Richard Garfield used this to design the games mana system and left this fun little credit to Larry Niven on Nevinyrral's Disk in the games original set
Similarly, if a cost includes causing you to gain life (like the alternative cost of an opponent's Invigorate does), that cost can't be paid
