Sphinx's Tutelage {2}{U}

Enchantment

Whenever you draw a card, target opponent mills two cards. If two nonland cards that share a color were milled this way, repeat this process.

{5}{U}: Draw a card, then discard a card.

“You’ve never considered the implications of dealing with another telepath, Jace.”

Colorless is not a color, so putting two colorless cards into a graveyard won’t cause the process to repeat. (2015-06-22)

The process will keep repeating as long as both cards share a color and neither is a land card. (2015-06-22)
