I have wrote this suggestion in the past, and will keep suggesting it with the hope you will consider it. The coding cant be that complicated.
A TC Spell called "Reverse". Make it expensive in gold, pips, or rare- but please bring it to reality.
If a wizard going second casts it- they stun the wizard going first for 1 one round. Now the order changes "reverses" and the second wizard now goes first. Like UNO. Its the best answer for the attack order that gives an undeniable advantage. If the other wizard happens to have one they can reverse the order.
