You may have up to 5 of any colorless card costing
less than 7. Ignore any color restrictions for cards
in your deck if they're colorless.
Eminence—You may pay {c} instead of paying for
any other color in any manacost and whenever any
card you control creates an Eldrazi Scrion,
double the number of Scions created by that card.
{2}{c}, {t}: draw cards equal to half the number of Eldrazi Scions you control rounded down.
