I would give this card a 3 out of 5, neither of its moves are too great or overpowering but I do like using the Lost Zone and the ability to retreat Giratina out for free by using Strafe
Primeval Spawn Theyve gone a long way to make sure Primeval Spawn cant be abused, like reanimation, blinking, or Tooth and Nail
I recommend proxying pricier cards like ACE SPEC Trainer cards and Tropical Beach to make things more affordable
Given that two of the initial reveals are Angel-type cards, and the other is a Dryad with life gain ramifications, I fully expect this deck to go heavy on these strategies and include some more Angels alongside plenty of ways to gain life
#4 Counter Catcher Keeping in theme with cards that are widely used, Counter Catcher isnt nearly as powerful as Prime Catcher, but its still a strong item card that is especially powerful in decks that dont need to come out the gate firing (like Charizard ex)
