Juggernaut, Unstoppable Force

Trample

Juggernaut, Unstoppable Force attacks each combat
if able, can't be sacrificed, and can't attack its owner.

At the beginning of each player's upkeep, that
player gains control of Juggernaut, untaps it, and
puts a +1/+1 counter on it. It gains haste until end
of turn.
