japanese gym heroes booster box Eevee Special S6a Shield series Gym Heroes (TCG) - Bulbapedia,

Knowing the best starter pack to choose first in Pokmon TCG Pocket can really help build your card collection, especially if you're planning on partaking in the competitive side of TCG Pocket

This card will eat removal, I guarantee it, and it deserves that respect and more

I think one of the reasons for that is simple

3 Trainer Trophy card were handed out to runners-up in 1997 competition

Using this on an Extra Deck monster though, will pretty much guarantee the bounce as some decks only rarely have more than 1 copy of a boss monster in the Extra, unless its like Labrynth with Loading

If you were lucky, you had maybe one Mirror Force in your deck, which left room for a stew of lesser battle traps like Negate Attack, Draining Shield, and even Fairy Box
