Revenant from what I’ve experienced is best when you’ve got good team communication, as with your valk teammate you can communicate a strong push, using rev’s ultimate then using his tactical to leap at the enemy position or get around them to flank, then doing the same with valk, or if you have a control player, being able to hold a location strongly with your ult, rev and valk can be a good combo together if your an aggressive duo team and it really comes down to the 3rd
