Unsullied Army

As an additional cost to cast this spell, discard a
Dragon creature card or pay {5}.
Create five 2/2 blue Human Soldier creature
tokens with hexproof.
The Unsullied are eunuch slave soldiers, trained from
a young age in Astapor to unquestioning obedience
and martial prowess. They are sold by the century or
the thousand. They make excellent guards, do not loot,
and will never rape.
