I have read a related post in this site but it doesn't clarify if this can be done or not because for one side it says: If the card is legal then the card has black or white borders and then it says: Artistic modifications are acceptable in sanctioned tournaments, provided that the modifications do not make the card art unrecognizable, contain substantial strategic advice, or contain offensive images
They did a great job of representing this moment with Shelobs effects
The card itself looks pretty good to me
At the Secret Lair panel, Wizards of the Coast announced cards based on The Office , Furby, and certainly the most Polygon-coded crossover, a collaboration with PlayStation for cards based on The Last of Us, God of War, Horizon, and more
Ultimately, while this can be effective, Runic Armasaur isnt impossible to play around or kill
Its Phyrexian mana lets even non-black lists use it for just 1 mana and 4 life to kill most creatures outright
