I am looking for help with reviewing sets and/or maintaining Lore Seeker and the Big Custom Box. If you're interested, please contact me in #general in the Custom Standard Discord. —Fenhl
Creature - Elemental
Untapped creatures can't block.
Tapped creatures can block.
Collector Number: 64
Siege Elemental's last ability allows you to ignore only a creature's tapped status when determining if it can block. It doesn't allow a creature to block a creature it couldn't otherwise block.
Once a tapped creature has blocked, untapping it won't cause it to stop blocking.
