The Shining Darkness part 2

So X-Sabers seem to keep getting supports TCG exclusives. While Boggart Knight was decent the new card is crap. Saber Vault pumps up X-Saber attack points by 100 for each level they have. So Gottoms is a 4000 beater. Okay. It has no other effects and can easily destroyed since its a field card. I used to run X-Sabers and I would really like to toy with Boggart Knight but the Saber Vault is useless.
