Most of the outside assistance cards allow you to use a text or phone call, but this one requires actual human contact
If a creature has an omen in its text box, you can choose to either play it normally, summoning it as a creature, or to play it as a sorcery or instant, as described in the omen section of the card (the left side of the text box)
Many spells return creatures to their owners' hands in blue, so to choose this one in particular, you are either playing +1/+1 counters in a UG deck, a blink deck, or both, and you get an excellent blue board wipe
