Hi @Migdad: There is still 10 days for the tournament to end. With the incubators you win from battle, the total DNA and coins would far supersede the prize for 4250 trophies.
Your team seems decent to hold up that trophy range. Focus on catching stegosaurus, apato to evolve your Stegodeus. Try leveling up more drinks from your team by hunting in those specific local zones. Don’t stop unless it’s the last couple of days.
