Flying, trample
Each Horse, Unicorn, and Pegasus creature you control has flying, and is a Horse Unicorn
Pegasus creature in addition to its other types.
{g/w}: Target Horse, Unicorn, Pegasus, Centaur, or Knight you control gains flanking until end of
turn. In addition, as long as it isn't attacking, that creature also gains horsemanship until end of
turn.
