So, I've been think of cool modes n ways to make the game more interesting, this one came to my head when I was playing Dota last night.
Imba stands for imbalance, and it's a just for fun mode, like Infinity, Pauper, Merged and Hyper(which is now gone).
This is how the mode works:
All card's purity decrease by 1. (all 1 purity becomes factionless, but it'll still have it's faction type)
Hybrids and dual factions remains the same.
I know this will turn out to have many interesting combos, but it's just for fun, tell me what u guys think.
