Lord of the Reckoning

Flying, haste
Whenever Lord of the Reckoning deals combat
damage to a player or human creature create a
red 3/3 dragon creature with Flying and Myriad
(Whenever this creature attacks, for each opponent
other than defending player, you may create a token
that's a copy of this creature that's tapped and
attacking that player or a planeswalker they control.
If one or more tokens are created this way, exile the
tokens at end of combat.)
