Ominous Prophecy

All zombie creatures cost {1} less to cast.
At the beginning of your upkeep, if you control
at least 5 zombie permanents, or if there is a
Hans Lichttrager in your graveyard, sacrifice this
to summon Hans Todestrager from your deck or
hand.
"I cannot believe that bastard is back."
- Garr, the Storm Shepherd.
