Jirachi HL would be nice, but its absence is somewhat compensated for by cards like Budew and Chingling. They don't allow you to bypass the rules of evolution like Jirachi did, but Budew can grab Candy, and Chingling can find Celio/Bebe/Elm to get those evolutions into your hand. Wager beats them, of course, but it's better than nothing. And I'm not seeing a lot of decks maxing out on Wager right now, anyway. Only a few can get away with it, and half the time it backfires, so Chingling provides decent support even with hand disruption back in the game.
Long story short, we don't need Jirachi back to balance the TCG, especially before BRs have even started. We don't know what the metagame will be (although this is probably the clearest it's ever been pre-season), so we can't say anything, yet.
