Deathsaber Colossus

Whenever a creature dies, put a +1/+1 counter
on Deathsaber Colossus.
Whenever Deathsaber Colossus attacks, if it has
three or more +1/+1 counters on it, you may put
a counter from among first strike, reach, or deathtouch on it.
As I swing my sword, Abathra grants me more power.
