Naming Screen (Unknown Event RW06a) - Rare Magic: The Gathering Card

As a creature token you control enters, name it using up to four letters. (It keeps its types. It just has a new name. Remember this is a family event.)
When this enchantment enters, create four 1/1 colorless Hero tokens.
Each creature you control that doesn't share a name with any other creature you control gets +1/+1.
