Master Reality

Master reality is another niche but incredibly strong power. It works best with battle hymn, as the card that is generated every single turn is upgraded. It obviously works well with any cards that create another card, but it works best with dead branch, especially since many of the cards that get created in the watcher are also then exhausted themselves. This is a game breaking combination. On the other hand, many decks do not require or benefit from master reality, so make sure you have enough create effects to make this power worth it.
