I stumbled upon 2 Youtubers getting into Infinity Wars: Merric and GUD. Both play a wide variety of games on their channels. The former has a lot more videos than the latter on Infinity Wars as of the time this thread was made, and even then GUD's Infinity Wars videos are collaborations with Merric, but since GUD's subscribers are also keen to watch more of IW, his channel is also something to look out for.
Here's Merric's Infinity Wars stuff
, and GUD's "Mondays with Merric: Infinity Wars" Episode 1
and Episode 2
, which can also be seen from Merric's perspective at here
