mtg banned offensive cards Every Commander Card Unholy Strength from Alpha (1993),

It doesnt matter if you damage or destroy a creature or attack your opponent directly

Its a decent curve-filler in typal decks, which could come up in Standard, and will come up in Commander

Cascade, cascade (When you cast this spell, exile cards from the top of your library until you exile a nonland card that costs less

And while theres no place for it in modern decks (if you really want to gain life per turn, there are better ways to do it), its an interesting bit of MTG history behind it so much so that Wizards reprinted it in the Brothers War: Retro Artifacts set

That includes both how complicated and how expensive it is to master
