Smoldering Stagecoach Smoldering Stagecoach is kind of nuts because this red artifact gives cascade to the next instant and next sorcery spell you cast this turn
For example, if you discard Carnage, Crimson Chaos, you may cast it from your graveyard for the remainder of the turn by paying just rather than the normal cost
You only need other creatures to make it good, which is trivially easy for most Limited decks
It allows you to grow your creatures to unlock board stalls, while enabling some very interesting synergies by dishing out creature abilities to your team
Its a heavily-played card in formats where its legal, and thats mostly Vintage, Legacy, Cube, and EDH, where its a Game Changer
There's also what Wizards refers to internally as ' snap-on equipment .' This isn't a named mechanic, but rather refers to the type of equipment that automatically attaches to creatures once it enters the battlefield, like Embercleave or Mithril Coat
