I would suggest that there should be some kind of special mode that gives battles with special rules to make the game more interesting.
The original idea comes from the card game spectromancer (first campaign is free to play):
Some suggestions for changed rules might be:
You or you opponent has at the beginning of the game some creatures maybe normal creatures or maybe special creatures that cannot be used normally.
As examples:
on every side one creature with 0/100 and gravity pull.
On every side one 10/10 creature with momentum and immortal at the begin of the battle.
Changed Rules some suggestions:
No shields / Weapons / some special abilitys do not work / all creatures and permanents get immortal when played.
All Pillars create random color / colors in a special way after changed rules / on both player scrambler is used every second turn / only monocolor game for both player (all pillars give the color of the mark).
The damage a creature deals is random / a fixed number.
Weapons / shields have a random effect instead of theyr normal effect when activated.
