We'll have, oh, let's say 5 dragons. They each start with 10 hit points. What ou do is "hit" one (remove a point) and "heal" another (give it a hit point). Once a dragon hits "0" it loses and we romove it. Once you tell us which you're hitting and which your healing, pos the total for all the dragons again.
So an example:
P1: Hits green, heals red!
Green: 9
Red: 11
Ect:10
Ect:10
Ect:10
P2: Hits red, heals green!
Green: 10
Red: 10
Ect:10
Ect:10
Ect:10
Got it? good! let's start with these dragons!
