Ildaine, Shadowsong Heir

Deathtouch
Elf assassin creatures you control have "{b}: This creature gains shadow until end of turn."
Whenever you would make an elf creature token
you may choose to make a 1/1 black elf assassin creature token with deathtouch instead.

In Briarwood, the Shadowsong family is well known
for being shadows among the treetops.
