This is one of the best Trainer cards ever printed, and possibly the best Supporter. It's infinitely useful, and it's ONE CARD that solves both of the two most common "lack of consistency" problems seen in this game since Base Set: lack of Energy and lack of Basics on the bench. It even gives you the coice to ignore one of the two, and pick 2 of the other! Castaway and Mentor were awesome because they could grab several different kinds of key cards (Mentor could do Energy in form of Holon dudes, and basics, while Castaway can do Tools, Supporters and Basic Energies), but this card is superior because it, without any drawbacks, gets you a BASIC Energy (which is arguably better than a Special Energy most of the time) and a Basic Pokémon.
Enough rambling, I don't need to justify my 10/10 any more.
