Banish!

Another potential 'problem' with Force Hold would be an opponent the uses teleport to move the held creature around (my wizard often has teleport bound to his Mage Wand).

Good point.

Another consideration I didn't mention is the cost to put it in your spellbook. Wizards can put in banish for 3 spell points and force hold for 4. All other known mages put banish in their book for 6 and force hold for 4 (except for the forcemaster for whom it cost 2).

Banish is a game changer. Trust me. The cost is worth it to remove a creature that costs 14+ mana. Think of it as killing a creature for 3 turns. I would put it in my spellbook if I could.
