Katabatic Winds - 109 R VIS

Phasing (This phases in or out before you untap during each of your untap steps. While it's phased out, it's treated as though it doesn't exist.)
Creatures with flying can't attack or block, and their activated abilities with {T} in their costs can't be activated.
Wind will win, whatever we wish.
