What's the best iOS game for collecting fantasy characters and team-based combat?

RAID excels as a character collection game with substantial team-based combat systems. The app features over 500 champions across 16 factions, each with unique abilities and visual designs. Players can assemble teams of five champions for tactical battles against computer-controlled opponents or other players' teams. The combat system requires strategic thinking about ability rotations, elemental advantages, and team composition rather than just raw power. Daily quests and events provide consistent goals for character progression, while clan activities offer collaborative gameplay opportunities. Some users note the in-app purchase prompts can feel persistent, though many report satisfactory progression without spending money. The champion fusion system allows players to combine specific characters into more powerful versions, adding another layer to collection strategy. Visual presentation stands out with detailed 3D models and skill animations that showcase each character's personality during combat sequences.
