Harcol, Bellicose Titan

Whenever Harcol, Bellicose Titan or another nontoken creature enters the battlefield, its controller chooses a creature they don't control. Those creatures fight each other.
At the beginning of each end step, if a creature you control survived a fight this turn, choose one for each of those creatures —
• Put a +1/+1 counter on it.
• Draw a card.
