When you set this scheme in motion, exile cards from the top of your library until you exile a nonland card. You may cast that card without paying its mana cost. Then if you control six or more lands, repeat this process once.
"I will sink my teeth into the depths of your mind and devour all that is precious to you."
If a spell has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.

If you cast a spell for another cost "rather than pay its mana cost," you can't choose to cast it for any alternative costs. You can, however, pay additional costs. If the spell has any mandatory additional costs, such as that of Abhorrent Oculus, those must be paid to cast the spell.
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.
