Onatah, Anaba Shaman

Landfall - Whenever a land enters the battlefield
under your control, Minotaurs you control get
+1+1 and trample until end of turn. If that land
is a mountain, they get +2+2 and trample instead.
{1}{r}, {t}: Onatah deals X damage to any target. X
is equal the number of half the mountains you
control rounded up.
Partner (You can have two commanders if both have partner.)
