for my suggestion
I'd like to see a list of exactly what happened in the battle int a textlog, same like they do on poker sites...
That was after a bunch of battles you can go back and see exactly what was done and how you lost or won.
it could be a simple log file this
A starts out with 22 mana Summoner: X, MonsterX1 (lvl and abilities) ....MonsterXn 2 ....
B starts out with 24 mana Summoner: Y, MonsterY1 (lvl and abilities) ... MonsterYn 2 ....
round 1
MonsterX attacks MonsterY with Monsterxability with lvl, MonsterY Deflects z and shield reduces u
MonsterY was eliminated from the field
....
The fact that there is replay means the log is already stored it just needs to be readable and downloadable instead of playing it.
