New to the game. Any suggestions?

Hey Reddit, so last year or so, my friend introduced me to MTG. She taught me the rules, we played a few games (she won, obviously) and I kind of forgot about it. Recently I've been wanting to revisit. I downloaded the app because I don't have anybody to play with currently and I started playing online. Working on making a black and white Orzhov Afterlife deck (if my terms aren't quite right please forgive me, just basing that off of the base deck I got from Amazon) are there any suggestions for beginner friendly but effective cards/strategies I can use when I meet up with my friend again?
