Kordran Juggernaut

Kordran Juggernaut can't attack unless you
control a mountain.
Tap an untapped mountain you control:
Kordran Juggernaut gets +1/+0 until end of
turn. If you activate this ability three times this
turn, Kordran Juggernaut gains trample and its
damage can't be prevented until end of turn.
