Iron Rain

Play all creature cards from your hand
without paying their mana cost. They each gain
haste, and must attack this turn if able. The base
power of each creature summoned this way
becomes 2 until the end of turn. Spells your opponents cast that target those creatures have a
mana cost of {0} until the end of your combat
phase.
"Tell all who will hear, the Reaper sails to Mars. And
he calls for an Iron Rain."
