Silence is a great card in these types of decks (at least in my opinion). Well played, Silence can turn a battle, save your Golems, prevent a Miracle, or stop DimShield chains. A Minor Phoenix is just another attacker, with (limited) synergy with Cremation.
The first version doesn't have Nightmares, while the second version doesn't have Silence... so I guess there's a version for either preference (Silence or Nightmare).
