Blitz List – sure to win teams
With every new character, more and more possibilities for making a viable Blitz team emerge. After thorough research, I have figured that the majority of players require a Blitz list of teams that will provide the highest number of wins per rotation.
My idea is to exploit all available characters. In Blitz, they don’t need to be fully improved to provide you victories because the power of enemies scales with your power. In other words, a Blitz win is a Blitz win. The power of the team could be 1 million or 30k, and the effect will be almost identical considering current Blitz events. Obviously, you will earn fewer points if your strength is lower, but currently earning points is not the priority. At the moment, the priority is to have the most wins from the single Blitz rotation.
Having all this in mind, I will suggest to you the list of teams that should grant you the highest number of victories per rotation. This list will be updated accordingly with every new update and every new character.
Sure-to-Win Blitz teams
At this moment it is possible to assemble 46 different teams. For some teams, I may use the same characters because it is acceptable to have 3 -4 characters that are used in another team. You have your Blitz charges for spending. Having 4 characters in 2 teams will cost you 240 Blitz Charges per day in total if you have 8 rotations. That is acceptable and leaves you enough Blitz charges for using on teams that are emphasized in Quick Rumble Blitzes or other Blitz Events.
In the current list, we will use Apocalypse, Doctor Doom, Dormammu, and Magneto in 2 different teams to maximize Blitz’s efficiency and provide you with the most viable options. Teams are listed from top to bottom according to their strength and their chance to provide you with certain wins. Teams on top will win always on Blitz Difficulty 8 and as the list goes down, their winning potential goes down also. Nonetheless, at the moment, all mentioned teams but A.I.M., Kree, and GOTG should have a 100%-win rate.
There will be 231 characters in the roster after the upcoming update. Unlocking Apocalypse will allow you to assemble 2 sure-to-win teams from otherwise underpowered characters in the current meta.

Conclusion
I am aware that many of our readers do not have all the characters unlocked from this list. I am also aware that many of those characters are still on level 1. My advice is to improve every character you unlock on level 30, or even better level 45 (500k gold total investment) because that will be enough for using them in Blitz. As I said, the strength of opponents in Blitz scales with your own power, so even the slightest improvement will allow you to use all characters from your roster in Blitz.
This list will be regularly updated with every new update and every new character. You should have this in mind the next time you need help regarding Blitz teams.
Thank you in advance and thank you for all your support till now. Without you, this wouldn’t be possible!
