Historically, the Color has been more focused on destroying Artifacts than on working with them
Whites a color big on Enchantments, so the argument that more white Enchantress cards would break it to me falls short, especially when it comes to EDH and the relative clunkiness of temporary enchantment based removal (pro tip: its not very good)
That's not nothing, but it's also not that abusable since Silas Renn will at best be able to do it twice in a turn assuming he has double strike and can get past blockers
Sephiroth, the Savior (Atraxa, Grand Unifier) This one I'm surprised at as well, but because of how low it is
This may change what effects can apply to them
If youve played the set before, I know Ill be seeing you in the queues this coming week
