The Secret Unit Economy
Secret Units (like Igros) are the ultimate prize in Anime Vanguards. Because they are not guaranteed by pity, their value is incredibly high. A common trading strategy is to hoard Secret Pity (if applicable) or save Gems for a "Double Luck" event before pulling. If you manage to pull a Secret, consider selling it immediately if the banner is new, as hype drives prices to their peak in the first 48 hours.
Trait Rerolling: The Real Gamble
Traits like Monarch, Solar, and Deadeye are game-changers. A Monarch trait can double a unit's DPS. Smart traders buy "clean" Mythics (units with no/bad traits) for cheap, spend their saved Reroll Tokens to hit a Celestial trait, and flip the unit for massive profit. This is risky but offers the highest ROI in the game.
Shiny Hunting for Leaderboards
Shiny units deal bonus damage, making them mandatory for top leaderboard runs in Infinite Mode. If you are a casual player, selling a Shiny Mythic to a competitive "whale" is often better than keeping it, as the Gems you get can fund an entire team of standard meta units.
Evolution Material Flipping
High-tier evolutions require specific materials (Essences, items from Raids). These materials are often tradable. During new updates, players rush to evolve the new unit. Stockpiling common evolution materials before an update drops allows you to sell into this demand spike.
Limited Banners vs. Standard
Standard banner units will return. Limited Banner units might not. Always prioritize trading for Limited units if you want your inventory to appreciate in value. Standard units depreciate as more players unlock them over time.
