How do I keep a streak on 3v3 arenas on Marvel Contest of the Champions?

Solution 1:

I have found another method, which is a compilation of all the methods I've seen so far. My goal is never use units to look for other opponents. I don't use sandbagging anymore.

• Battles 1 to 9 - It should be easy.
• Battles 10 to 12 - I don't use sandbagging. I just play the lowest 3* teams.
• Battles 13 to 19 - I use 3 4* 3/30

From battle 20 and on I just keep my team total PI over 4200 (with no synergies or boosts).

This is not the fastest method because if you don't have enough teams of 4*s you'll have to wait for their cooldown.

Solution 2:

Well, I guess I'll just post what I found on Reddit:

• Battles 1 through 8 or 9, easy.
• 9 through 15, sandbag. Play 2 champs around the same, and 1 really weak one. If you get a match up too difficult, pay the credits for a new matchup. I prefer to use champs that are around 1200 PI each.
• 16, 17 and 18, Keep your team PI above 5500. Typically you need to use 4*s that are 3/30. If your PI is not above 5500, you will get the monster 14,000 PI teams.
• From 19 on, you can drop down, but keep your PI above 4000. All these numbers are without any buffs active. If you turn on any buffs, the PI requirements go up.

This should work for the current version 5.0. It is the best technique I found so far.
