Cards like Malicious Affliction, Reaper from the Abyss, and Tragic Slip are much more powerful when you can toss away one of your creatures or tokens to make sure its online
The only way around this kind of thing is a clone like Spark Double, which can copy legendary creatures without issue because it removes the legendary typing when it copies something, or another way around the legend rule like Mirror Gallery or Sakashima of a Thousand Faces
The game has all cards released internationally from the Black & White expansion ownards, initially with only cards in the Sword & Shield expansion series being playable, with new products being released in periodic updates
While it wont stop untargeted mill, and it cant stop someone killing you with Commander damage if they somehow play a card that says damage cant be prevented, itll stop basically everything else
