Treasure card versions are No PvP, however, if you are of that school and have that specific spell, there is nothing to prevent you from casting it, as you have earned the level and right to use that spell.
In pvp individuals continue to use cards that are mark no pvp. Such as: Talos, Insane Bolt...etc.
Thank you for looking into this matter
Veoff,
Are you saying that TC's that are band are still being used? Or are you saying that a Storm Wizard can still use Wild Bolt and a Myth Wizard can still use Talos in PvP?
