"Take up the quill, and feel your future flow into the runes."
If Rubinia Soulsinger stops being tapped before its ability resolves — even if it becomes tapped again right away — you won't gain control of the targeted creature at all. The same is true if you lose control of Rubinia Soulsinger before the ability resolves.

Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
