Rhyperior

Trample, Evolve

Rhyperior can't be blocked by creatures with 3 or less power.

When Rhyperior enters the battlefield, Creatures you
control with 5 or more toughness obtain a sturdy counter.
Whenever a creature with this a sturdy counter would be
destroyed, remove the counter instead. The creature's
toughness becomes 1 until the end of the turn after losing
this counter. Creatures can't have more than one sturdy
counter on them.
