>>45368810Theme deck battles range anywhere from overly drawn out and dull, to quite strategical and engaging depending on which you play.
The recent Zacian,Zamazenta, Rillaboom, Inteleon , Groudon, Kyogre deck are all good choices.
The upcoming vivid voltage ones are good too, especially for Charizard's.
I'd still advice you to spend the 10€ extra or so and instead get league battle decks. They're much better all around from gameplay to value to the dice and tokens included.
If you want to take it a step further you could buy championship decks but the gameplay might be too fast and complicated.
