I have
The Stranger with gauntlet and time gem
Aim renegadex2
and was wondering how to play this team.
The idea is to get into a corner, and arrange the barrier builders so that the Stranger is not accessible, and then use the stranger to take some action in the corner to cause the Stranger to get some power and then attack. But I have some questions about the specifics.
I will be looking at the team myself in the meantime.

1.what is the formation i should take with the renegades?
2. How should I pick which corner i should choose?
3. What action does the stranger do to TURN?
4. How do I decide when I change size and attack?

You can give the Stranger move actions to move 0 squares and take a token. As for the formation, Stranger in the physical corner of the map, the Renegades as close as possible to him. That takes up 3 squares. You can barrier the next diagonal with 3 barrier markers, using the 4th to make it harder to break through at some point in the line.

Make him colossal so he can push with 2 tokens. Pick regen with power 2 and 3 to heal up.
