Derek Wyrmsbane

Haste
Whenever Derek Wyrmsbane attacks or blocks,
at the end of this combat phase destroy all other
creatures with flying that attacked or blocked
this turn.
Despising the use of sunwebs, the Emberhammer
clan's most hot-headed champion is said to bathe
his weapon in the blood of dragons, infusing it
with the fiery spirit of each slain beast.
