DM gifts: not another dragon chess game

[Desteplo]

You all appear in a space between. The walls are like a thin layer of oil on water; shimmering rainbows. four sets of armor lay on the floor, 2 sets of each
-a hammer and shield
-a lance and shield
-a staff and robes
-and a greatsword

You realize this isn't a normal game of chess :
-you will take control of a unit
-your goal is to overtake the throne.
-when your unit attacks after you dealt damage if your target survives then they counterattack and vise-versa
-you will have 5 minions, and you 4
-they will have 5 minions, 4 class units and a king

Atk/def

Hammer: 4hp, 1/1 heals other unit by 2

Lance: 5hp, 2/1 can not provoke/initiate counter attacks

Staff: 3hp, 2/0 range

Great sword: 6hp, 3/0 cleave (hits 2 guys)

Minions: 1hp 2/0

What is the board? What are the "1/1" numbers for the weapons? When I attack and the enemy counterattacks, do we keep cycling through that until one is dead, or just a single attack and counter? Does the greatsowrd provoke counters from both targets? Do you capture the throne by threatening it (as in chess) or by moving onto it or actually attacking and defeating a unit? How does each unit move?
