I'm not keen on showing my opponent my hand most of the time, but to get rid of all your opponents trainers? Win (use yours up first though).. Also you get a nice peek at their hand. Although trainers take up around half an unlimited deck, it would get rid of most of their hand, but they'd bring it back pretty quickly anyway. 4/5

There aren't any popular unlimited decks that rely on status effects. Don't bother. Just use a switch, send out a baby and then send it back. Easy. 2/5
