Remote Relic

When Remote Relic enters the battlefield or is put into your graveyard from anywhere, deal 2 damage to each opponent then untap a basic land you control.
{2}{r}{r}: Remote Relic becomes an X/X Red Construct creature with Trample until end of turn, where X is the number of tapped non-basic lands on the battlefield.
It stands idle, king of the empty wilds.
