How this works is whenever Shredder, Shadow Master attacks a player, each other player at the table gets a non-legendary token copy of Shredder, Shadow Master, which enters tapped and targeting the same player
I agree that CCGs have a fundamentally different model, but in the standard CCG model, yes, there are ultra-rare cards, but most anyone who is a serious player will be buying enough copies to end up with one or more of them, and no one card should be significantly better than the others
The Jeskai mode is capped at one card per turn (sans double strike or extra combats), but 3 mana for an extra card every turn is solid
Sam Black: Fact

Like many black kill spells, this spell can't target black creatures
