In red tempo decks, its both ramp and card advantage wrapped in one aggressive package
The new Core Set 2021 versions are about 10 times better than the originals and actually seem powerful enough to form the base of a competitive Standard deck
If it wasnt for the remakes of these games, Id say theyre still worth a play, even if the black-and-white graphics and absence of some of the deeper systems like split Physical/Special Attack missing can make them hard to go back to
Its first attack, Storm Bug, is able to deal over 100 damage while requiring only a single Energy , and it also allows Flygon to retreat without needing to discard said energy
While this is already valuable, the new adorable and threatening art may boost this value even more
The TCG version also introduces new members/support for the "Ecclesia", "Familiar-Possessed", "Mystical Beast of the Forest" and "Swordsoul" archetypes
