Wouldn't it be simpler to allow the use of any scrolls as soon as 2 max Mage Guilds or a Mage Guild of the scroll's level are built or captured? Otherwise, collisions are possible even in solo play—for example, you start building Mage Guilds with double castle, build up to 2x3, and then capture a Tower. And what now? Build a level 5 Mage Guild just to use Dimension Door?
