This can be very strong in decks that mess with your land base, moving them into and out of the graveyard multiple times a turn
It's a game winner
For example, Tamiyo, Field Researcher lets you cast spells for free for the rest of the game, and Nicol Bolas, Dragon-God can kill each of your opponents as long as they dont control a legendary Creature or Planeswalker
It protects your enchantments from countermagic, it's an enchantment itself so it has strong synergies with the deck, and later on in the game it's a great mana sink to start pressuring opponents
These decks are perfect for anyone getting into Magic (and the perfect follow-up to Welcome Boosters in terms of article flow)
Led by dictators, tyrants, or military generals, this deck is full of ways to build your army of humans to fight against the other factions of the nuclear wasteland
