Absolutely correct hit ! Lighsworn must be erased from WC ! Lighsworn WC is a very oppressive deck which almost every turn go plus 3 with a field negate and a monster that can go over 6000 defence ! Well done Konami !
Charge of The Light Brigade has been broken since release. Thunder Dragon is the first victim of banlist because of abusing this card. Now Witchcrafters become another victim. And it's highly possible for some archetypes from future boxes being another one.
This will never happen because it is actually very balanced.
Why? Because not EVERYONE has it yet. It is a SR and expensive. The cost hard-limits this card already. No reason to limit 1.
If you really want Konami to limit Charge then try to convince ALL Duel Links players to buy 3 Charge. Then Konami will have to limit.
Oh yeah. This hit totally kills those WC deck with 30 cards format, with Solar Brigade, Lightsworn and Greener Grass.
I think it's a very fair hit. People abuse these games by putting cards where the don't belong. WC deck should be played with WC cards only, plus 2/3 generic spell cards. They are not supposed to combined with Lightsworn.
