If you're playing heroes i think aqua dolphin is the perfect choice, i don't always use him or his actual effect normal he'll be in my grave via prisma, or future fusion for divine neos. but when i do use him it's always helped me out i just think he's a good choice when playing certain kinds of heroes.
Besides... this is troll tech, if i used mind crush it wouldn't be that much of a troll card. the whole point is to use cards no one uses and make them work. (and also tick off your opponent)
