Stuck Together

When Stuck Together enters the battlefield,
choose 2 creatures. Those creatures now must be
touching at all times, and they are now sticky. Whenever a sticky creature interacts with a
non-sticky creature in any way (eg. blocking, fighting, targetting...) then that creature becomes sticky and must always be touching the
sticky creature. Whenever 2 or more sticky
creatures stop touching, destroy them, all
creatures become non-sticky, and sacrifice Stuck Together.
