commando cloud walker arcane sapper fallen dominion mystic old curse drunken master war chief vengeance spirit shadow leaf. thinking about late game. I am level 86 and using these heroes in arena and grand arena. also savage one is good for raids. poisoned one and some others good for outland. depending on your interest, every hero can be useful.

For me, these stand out at your current team level as "top 10" imo:

Death Mage - crusade and PvE superstar, girl team
Commando - useful just about everywhere, girl team
Cloud Walker - great at blasting through front-liners when they're stacked too hard; and doppelgangers can get enemy ultis to go the wrong way, etc. v good
War Chief - probably the top tank out of the bunch you mentioned -- when you hit 53 anyway, his purple revive will make him a relatively tanky-ish physical DPS
Chaplain - important for crusade, can take a spot on your girl team too
Old Curse - magic beast
Phoenix - another magic beast
Frost Mage - pairs well with DM?
Mystic - another good pairing with DM for Crusade, etc.
Admiral - your girl tank (or at least your girl front-liner) and great end-game


If you have enough XP and gold to do more, figure out what you need based on where you're struggling most (crusade being the top priority, imo).
