Never-Ending Maze

Defender
Whenever Never-Ending Maze blocks a creature,
you may search your library for a creature that has
2 power or less and put it tapped onto the battlefield.
If you control Maze Runner, you may search for a creature with 3 power or less instead.
Stone by stone, it stands, a silent sentinel against the
maze's mysteries, its paths known only to those who dare to tread them.
