A gold macaw, a strong bird which looks harmless 😜😜
Another macaw in season 2. Targets here are hard. My current strategy is to recruit one more Rare (⭐⭐⭐) hero- at least Rare heroes for all 5 in the battle lineup. Uncommon heroes are just not strong enough for a sustained battle.
Like other games, winning gems will help you speed up and the summoning of Legendary Heroes.
