Nalus, Nature's Aberration

Shroud, trample
Whenever Nalus enters or leaves the battlefield,
for each player, choose a permanent they control
not named Nalus, Nature's Abberation. For each
of the chosen permanents, you create a token
that's a copy of the chosen permanent, except
it isn't legendary if that permanent is legendary.
If this card leaves the battlefield, or is put into
your graveyard or exile from anywhere, exile
it with a binding counter on it instead.
