Otto Octavius, Doc Ock

When Otto Octavius enters the battlefield, you
may put a +1/+1 counter on up to five other legendary creatures you control. Then, if you put
a +1/+1 counter on five or more creatures this
turn, put four +1/+1 counters on Otto Octavius.
Otto Octavius can block up to three additional creatures each turn.
We can't lose. This is our day, gentlemen... the day
the Sinister Six reigns supreme!
