I don't know of any games like this, but if you want to play on a PC/MAC I'd suggest downloading this http://www.andyroid.net/
It's a pretty good virtual of Android. You can play Heroes Charge on it quite easily.
I tried Magic Rush: Heroes for a while. A lot of the same basic premise, hero collecting via stones, pve, pvp, crusade, daily challenges. It's from an isometric view rather than straight horizontal like HC, and you actively target most ultimates rather than just cast them. On top of HC's mechanics they added some tower defense elements, world combat, draft/ban style ladders, digging for treasure, etc. It was pretty fun for a while but I didn't want to sink a lot of money into it to stay competitive.
