FChamp on Marvel Infinite.
Those let's be real here. most of the video is taking a massive dump on SFV.
FChamp says that his personal approach to team construction in Marvel Infinite is going to be:
Pick a character who is an all rounder (good at defense/offense, mobility, projectiles etc) and then pick a character that compliments that. From there he says that he will be using all 6 gems for different match ups and not be locked into 1 gem that he will use all the time.
Though I think in reality what's going to happen is that people will find a duo team that works with one specific gem very well. Like let's say Hulk and Strider with Space gem. Hulk for command grab mix ups with the Cube and Strider with Oroborus in the Cube. This was just a random example of course.
It's still going to take a while to figure out the top tier duo + gem combo. I am leaning more towards characters who just have a lot of good tools (like say Ultron) will just be picked a lot because they can just adapt better to different gem configurations.
