In regards to Momentum, I noticed that you mentioned that 14 (Ace) is the highest amount that can be moved. However, the amount moved from a Momentum Boost is not the Card Value of the Momentum card played, but the difference between the old Momentum card and the new one.

Example: Fighter A and Fighter B are 6 hexes apart. Fighter A has a 8 of Spades as their Momentum, Fighter B has a 3 of Hearts.
On Fighter A's Turn, he Momentum Boosts by playing a 2 of Diamonds. The difference between 2 and 8 is 6, so he moves 6 hexes towards Fighter B. He attempts a Strike but is unsuccesful.
On Fighter B's Turn he also Momentum Boosts first by playing a 7 of Clubs, replacing the 3 of Hearts. The difference between 3 and 7 is 4, so he moves 4 hexes away from Fighter A. He then spends his Action to Charge a card.
The Round ends, leaving Fighter A with Momentum 2 and Fighter B with Momentum 7. Fighter B will go first next round, leaving Fighter A wide open for a retalitory Blast.

I hope the above example helps. I also cannot wait to see your play example :)
