Bugs:
Ante up isn't working as you would expect all the time when there are multiple gamblers--stacking issue involving the modifier refreshing.  Let multiple Ante Ups on the same unit.

You can get negative gold when casting Ante Up.  The spell sometimes removes 200 gold instead of 100 for some reason.

Swapping Gambler's abilities to their half- or no- mana cost versions could potentially cause problems if there are existing Ante Up modifiers in play, since the ability they are attached to no longer exists.




Suggestions:
Incinerate should start at its full radius.

Add another voting option for "Vulnerable ancient" or something, so you can create a mode where you win by getting kills or destroying the ancient.

Add a graphic indicating how close teams are to winning if there's a kill-based win condition.

Add a "itemdrop" mode option, where a random one of your items drops on death?  Have to find a way around items getting muted, possibly by deleting the item when it's picked up, and remaking it for the new hero.
