It wouldnt be fair to judge a lot of the cards from Magics first few sets to something from the 2020s
You'll also want to sleeve your cards, and you'll need enough pre-sleeved basic lands for your players
The concepts are fun to speculate about, but I honestly can't see a nonbroken sword that gives protection from creatures or players making it to actual print

Crush your opponents with cards like Xenagos, God of Revels, Rionya, Fire Dancer, or Helm of the Host
