Nothing major, just an update of how to use Double Spell in the OCG.
Memories of the Duel King: Battle City has text different from the TCG’s current reading of Double Spell:
手札から魔法カード1枚を捨て、相手の墓地の魔法カード1枚を選択して発動できる。選択した魔法カードを自分フィールド上の正しいカードゾーンに置き、使用する。
“Discard 1 Spell Card, target 1 Spell Card in your opponent’s Graveyard; place the targeted Spell Card in a correct Card Zone on your side of the field, and use it.”
There’s no indication the TCG will be updating this card’s text to work like it, so it’s best to assume until further notice, it ,will never be changed.
(The TCG tells you to basically treat Double Spell as using the target Spell’s text.)
