The rulebook reads on page 25: "For example, the Mage Wand can only bind an incantation spell, so you could not bind an attack spell or enchantment to it."The text on the card Mage Wand reads: "Spellbind You may bind a non-epic spell from your spellbook to Mage Wand. As a quick spell, you may pay 3 mana to change the the bound spell."
That is actually exact the same text as on the Elemental Wand and referrs to no limitations of spelltypes at all. I assume I have to use the Magic Rule: the spell card always takes precedence ; )
