Baba Yaga's Hut

Haste, double strike, trample, indestructible
{9}{t}: Monstrosity 7
Baba Yaga's Hut can't attack unless it is
monstrous and you control a Wizard. Whenever
Baba Yaga's Hut attacks, Wizards you control
can't be blocked.
Centuries later, the greatest witch's hut continues
to roam... and slaughter.
