Around 13 packs right now. The main must of TEU.
Let you find once per turn a Trainer card. ANY trainer card in the 5 next card of pile. And then with Escape board, you retreat. You can even do a couple Jirachi a turn, then Guzma. It's powerful to get any item, tool or the supporter you need. Kind of Zoroark's Trade ability, it's "free" drawing.
A couple Jirachi can fit in ANY deck.
Zapdos is another good card. Pairing with PikaKrom or Lighting tool deck, actually you can make a deck based on Jirachi and Zapdos as once Jirachi's retreat, Zapdos hits for 80 for a single energy + Choice band + Electro power... 140 to GX, 110 to noGX. But you can use more than one Electropower per turn so can 1HKO a Lele GX for example with 2 Electro power. And you're giving 1 prize in exchange.
Pikachu & Zekrom is powerful. You can loose 3 prizes but, the GX attack let's you get 4 in a lot of cases, and even you could get the 6 over already damaged TTs.
Not just about TEU cards but, the most successful competitive decks lately are: Blacephalon, Zapdos variants, Pikachu & Zekrom (with or without Zapdos), Zoroark/Lycanroc and Malamar variants.
