Alright....new team. I wanna try this...
Adam Warlock
Mr. Majestic
Drax the Destroyer
(those are the phsical distractor guys)
Dr. Strange
The Doctor (from Authority)
Here's some info on the Doctor...
History:
The Doctor was an unknown force before Jenny Sparks found him. He is probably the most powerful member of the Authority. He has a connection with all of the previous Doctor's giving him a vast store house of knowledge. It was the Doctor who found the Carrier that the Authority uses as their base of operations. It is believed that the Doctor is from Amsterdam. He often refers to his homeland when casting magical spells. It appears that some of the former Doctors include Albert Einstein, Jesus, Genghis Khan and Nostradamus.
Powers:
The Doctor is a modern day shaman or master class wizard. As such he has vast powers which have allowed him to create force shields, convert people into animals, destroy the entire nation of Italy, open doors to other dimensions, heal the Carrier, and move objects telekinetically. In addition to these vast powers, part of the Doctor's mind is in constant contact with the spirits of all the other Doctors. There have been Doctors since the Dawn of Human Life
So Majestic, Warlock and Drax (who has a similar-to-Thanos invulnerability thing going for him) start pounding away while The Doc and Strange put up some shields and start casting. The Doctor can travel through time (he sent someone back in time in the comic I read and I read it on another bio i found)...so him and strange go back in time and...uh...hmmm....ok, got something.
They go back to when Thanos had a self-defeating personality. They recruit the other three guys to dish out some punishment (this is well into the past, so Thanos not only has no prep time, but he has no idea why he's being attacked). Then Strange, with a bunch more time on his hands, works with the Doctor to send Thanos into a pocket dimension, or just beat him within an inch of his life and call it a day.
There. My plan. Huzzah!
