1. Get Darkrai Vstar out as fast as possible.
2. Although dark patches are the most effective use of Darkrai's ability, do not be afraid to use it as a finisher. (retrieve: energy switch or choice belt)
3. Use Crobat Vmax to switch with Galarian Wheezing to stall.
4. Do not use galar mines unless destroying another stadium (path to the peak).
5. Wyrdeer is a finisher that can deal 320 damage with 8 energy.
6. The most important cards to get with Hisuian heavy balls are Moltres V and Wyrdeer.
7. If you already have 1 Darkrai Vstar on bench do not develop a second unless the current benched one is in danger.
8. Klara combos with Galarian moltres very well.
9. Energy switch can help get a second energy onto an active pokemon like Darkrai Vstar or Crobat Vmax.
10. Although the deck has powerful turbo tools like dark patch and crobat, at the end of the day the deck is relatively slow. The unusually high amount of pokemon and reliance on discard makes it hard to set everything up on early turns. play defensively for the start of the game but as it progresses and the engines starts heating up you can switch to a more aggressive play style.
