Last caress and here to help interaction

Radiance rules aren't published yet. This uses the printed card and current rules only, and it isn't a ruling on the new mechanics.

I can't find a card named Last Caress in the published card gallery I can search, so I don't have its printed text and can't give you the interaction. If it's a new-set card, its text isn't in my sources — whatever number or step it contributes is unknown to me.

What I can confirm on the Here to Help side: it's a Body [Hidden][Action] spell that lets you play a unit from hand to a battlefield you control, reducing that unit's cost by [3]. The unit must go to a battlefield you control (FAQ #3497), and the unit you choose isn't revealed until Here to Help resolves (FAQ #2921).

Give me Last Caress's exact printed text and I'll rule on the interaction proper.
