Tom Bombadil

Lands you control are indestructible.
At the beginning of combat on your turn lands
you control become 2/2 creatures until the end
of turn. They are still lands.
{t}: Sacrifice a land. Creatures you control gain
+2/+1 and vigilance until the end of turn.
"Tom was here before the river and the trees; Tom remembers the first raindrop and the first acorn. He
knew the dark under the stars when it was fearless,
before the Dark Lord came from Outside."
