Guardian Angel and Steraks are basically the same item. Prove me wrong.
Both make you unkillable sometimes and gives alittle bit of damage. Even when my team successfully kills someone with steraks, it's never directly, we wait until it wears off then we kill them. It makes Yasuo incredibly tanky since yasuo's typically build steraks or Frozen Mallet with Guardian angel.
and 
are the same item, they both give damage and crit
revive you?
