Iskandar Khayon

The first instant or sorcery spell you cast each
turn has cascade.
When another nontoken Demon, Astartes
or Cleric permanent enters the battlefield under
your control, you may sacrifice it, if you do,
each opponent loses life equal to that
creature's mana value and you draw a card.
" As the Warmaster's power grows in realspace,
my warp gifted abilities swell in accordance."
