I posted in this thread a few months ago, and I think my opinion is just about the same, minus the odd tweak. It's very easy to say "Jirachi is terrible because it has 90 HP and gives up 2 prizes", but unless you put some genuine thought, research, and/or testing into the card, it's also hard to say otherwise. Obviously, the worst-case scenario is that you start with a lone Jirachi, as at that point it is literally a free 2 prizes for your opponent and a waste of bench space for you, but the case could be very different if you know what you're doing with the card. It takes up only one slot in your deck, is searchable via Level Ball, and you don't NEED to play it when you get it or have the opportunity to get it, so if you play it down, it would only be your fault if the supporter you get isn't worth the two prizes. Not to mention that if you time your Jirachi perfectly, you should be able to get your supporter and set up to the point where your opponent can't afford to waste a Catcher and an attack while ignoring the powered-up attacker on your side of the field.
