Complete Scorching

Deal 7 damage to target creature. If a creature
dies this way, it cannot be brought back to the
field, to the hand, or to the library in any way.
Target opponent discards cards equal to that
creature's toughness.
The whole reason the people of Kaladesh came to
Tarkir was to study the dragons' fire for their pyromancers. Unfortunately, they got a little too close
to said fire.
