Not only is this card a sacrifice engine, but the Emblem it can provide pushes it into a different league entirely
V cards have higher HPs than their regular forms, can be played immediately like Basic cards, and can potentially possess stronger moves or abilities than they regularly have
This is also what makes board wipes so good in Voltron - so long as your Voltron creature is protected from them - as it evens the playing field back in your favor.
Additionally, the Steel Wing attack will reduce any incoming damage during your opponent's next turn by an impressive 60 damage
I wish there was just a little more support for it, like some reasonable cantrips that it could turn into good cardsmaybe something like Electrolyzebut you never know what the future might hold for Battlefield Thaumaturge
