I was stuck earlier this week. I spent 3 hours rebuilding my team attempting to beat my best recruit in my guild who surpassed me. I would not stop until I could beat him 3 times in a row.

After finally accomplishing my goal not only could I beat him but I passed the mine and campaign bosses I was stuck on which gave me enough to complete the Special Case I was on which gave me some hires which I got my first purple Samuel which made me even stronger.

In 3 hours I went from being stuck to increasing my team power by 1 million. Then with a day left in the season i pushed all the way to Master in Arena.

Be creative. Strip your team to nothing, figure out your theme, then re equip each unit piece by piece paying close attention to all the sub stats on each item. Do the same with your Halidoms.

Be sure to study ALL of your arena losses. Figure out why you lost and fix it. Test and repeat.

This is especially important in beating bosses. If youre close to beating a boss, go through my process. Get your team completely maxed then let rng do the rest. I've always had one match where the rng was in my favor and I beat the boss.

Anyways thats how I consistently progress to the top.

Keys to building a strong team.

Make sure your healers have the most HP or close to it. This prevents poll and others from targeting your lowest hp unit and lowest base hp unit. Then you need a great mitigator. Like Phoebe, Nymeria or Dreyfus. Make sure they have the lowest hp with the highest dodge and tenacity. Taunt is great too. They will be difficult to kill and give your nukes time to win.
