Garchomp is easily the most difficult card to find in NM condition from Plasma Freeze, with no recent NM sales, though there are multiple LP sales at the $125 mark
If that Digimon's DP increased to 7000 or more by an effect afterwards, can it attack or block?" No, it can't
It's a strong card if you put it out, so if you put it in a deck that's easy to put out, I think you'll be impressed by its high control power
It's solid, though, since you get to do two land drops in a turn
The thing is I have no idea what kind it is or where to get it - theres no brand mark on it and so availability may be an issue (If someone knows what Im referring to left me know and Ill add it here!)
After clearing the main storyline, you can start the game over with the same cards, recipes and character that you used in your previous playthrough
