Surprise Enchantment

Normal Trap

If you control a Spellcaster monster; activate a Continuous Spell from your hand or GY. If you control a Level 7 or higher Spellcaster monster, you can activate it from your Deck or banished cards instead.

This is an interesting effect, I like it. The new Spellcaster cards, for Endymion and for Witchcrafter both have Continuous Spells, so this could be their fourth copies (provided they even run 3 to begin with).

There's a Spell called Spell Economics and I've always felt like there's some degenerate combo out there with it that nobody has figured out yet, but this card could give whatever combo that may be some consistency... Seriously, Spell Economics is a hidden gem, I'm sure. 

The thing about cards like this, is it is only as good as what it searches. So, you have to think about every Continuous Spell out there, and then think about what it would be like if you could search it, as well as activate it during your opponent's turn. And what I like about this card is, it feels like it could be one of those cards that reawakens some old forgotten card, and gives it new life, which is one of the great things about YuGiOh in general, how every card has potential interactions with every other card that came out.

This card is only held back by being a Normal Trap, IMO. As pointed out above, being able to activate any Continuous Spell is deceptively good, and some decks shouldn't have problems with getting a Level 7+ Spellcaster on board to access the search from Deck. Heck, you can even get one with Destrudo and then going for an available Level 7 Spellcaster Synchro.
