Vine tree can't cast non-vine conjurations, right?

[Sailor Vulcan]

So I'm playing against someone on octgn right now, and they're saying that they thought vine tree could cast any non-vine conjuration since it can cast a vine creature or conjuration spell. They took that to mean "a vine creature or ANY conjuration", rather than "a vine creature or a vine conjuration". Please clear this up as soon as you can, I don't want to have to argue about house ruling it when I'm almost certain that it's not legal to cast nonvine conjurations with the vine tree.

Thank you!

The [mwcard=DNJ12]Vine Tree[/mwcard] can only cast Creatures or Conjurations with the Vine Subtype.

In my experience, as a general rule:

1. If a MW card says

"<Qualifier> <CardtypeA> or <CardtypeB>"

it ALWAYS means

"<Qualifier> <CardtypeA> or <Qualifier> <CardtypeB>"

2. But if a MW card says

"<QualifierA> <CardtypeA> or <QualifierB> <CardtypeB>"

it means "<QualifierA> <CardtypeA> or <QualifierB> <CardtypeB>"

as opposed to

"<QualifierA> <CardtypeA> or <QualifierA & QualifierB> <CardtypeB>"

It is actually common use in English, and perfectly fine grammar, for an adjective to apply to multiple nouns. Some examples:

The nurses have clean sheets and blankets.
Those are very ripe apples and oranges.
My friend has very pretty cats and dogs.

Mage Wars makes use of this, which allows them to save some space on the cards. So, in your question, the descriptive use of the Vine subtype applies to both creatures and conjurations. ACG actually did a really good job breaking it down in detail how this works.
