So i'm using this deck on MTG Arena. It has a few core set 2020 cards in it. It's a vampire deck. Was wondering if there are some other cards I should swap to to improve this. My deck: https://tappedout.net/mtg-decks/08-07-19-mxr-vampire/
You'll have more luck posting such threads in the Casual forum. Also, please post your deck list using the forum's tags, many people won't bother following links, so you lose many potential helpers.
