The decks I will be interested in trying with Faithless Looting are Creativity-Persist shells, Goryos Decks, Woodlands Combo, Jund or Rakdos Delirium and Breach Combo
MTG players can also give their strongest creatures Hexproof to stave off any removal effects, with green, blue and white cards all offering viable options at fair mana costs
If you do, return this creature from your graveyard to your hand
So, they are major wins for a lot of players, and major losses for others
That's all well and good, but if you can hang on to that Metalworker you often end up with eight, ten or even more mana by showing your opponent most or all of your hand
