Which Android app is best for a hero collection game with team strategy and PvP?

Hero Wars is a strong contender for players seeking a hero collection game that emphasizes team composition and player-versus-player competition. The core appeal lies in assembling a roster of over 50 heroes, each with distinct abilities, and strategically combining them to exploit synergies for both the campaign and competitive modes. For real-world play, this involves carefully balancing tanks, damage dealers, and support units to overcome specific enemy teams in the Arena or Grand Arena. A significant strength is the game's approach to free progression; consistent daily play yields steady rewards for leveling and gearing heroes, though the pace naturally slows in later stages. User feedback consistently praises the strategic depth and the fact that spending money is not mandatory to enjoy core content. However, the experience is not without friction. Several reviews indicate that the ad-serving system can be unreliable, with ads sometimes freezing even on stable connections. Additionally, specific modes like Legends Draft are noted to have persistent bugs that can frustrate players. For those who enjoy theory-crafting optimal teams and testing them against others, the strategic PvP systems provide long-term engagement, even if some interface elements feel a bit dated.
