Kong, Guardian Beast

Riot, trample

When Kong, Guardian Beast attacks choose two:
•All creatures able to block Kong, Guardian Beast do so.
•Put a land from your hand into the battlefield tapped.
•Sacrifice an artifact, Kong, Guardian Beast gets +X/+0 until end of turn where X is that artifacts mana value.

You may sacrifice a land rather then pay the equip cost of the first equip ability you activate this turn targeting Kong, Guardian Beast.
