I managed to try a certain game mode with my gaming group. I'm not sure about the overall balance of the concept, but the game became ridiculously fast after we implemented these modifications.
Mage Wars Extreme (We didn't really know what to call it LOL)
changes:
1. The quickaction token is not used (you'll see why in a few)
2. Much like creatures, the mage can use his fullaction token to move or attack (physically/weapon), but not to cast spells
3. Mages can cast as many spells/creatures as they can, provided that they can pay for it.
4. The planning phase is removed.The Mage has his spellbook and its contents ready for casting/summoning at all times
-Now, mages can run around while casting spells.
5. Mages can't cast a full action spell after moving once. So you must not move if you want to put out creatures or fullaction spells like firestorm
Optional rule
1. The quickaction marker can be used to make an incantation quick cast spell quicker. (once per turn)
ex. Mage attacks with wand. opposing mage flips quick action token to cast dissolve on wand.
Just a random experiment. Hope you guys like it
