Predatory Amalgamation

When Predatory Amalgamation enters the battlefield, exile the top card of target player's library. Put a number of +1/+1 counters on Predatory Amalgamation equal to the exiled
card's converted mana cost. Then, Predatory Amalgamation fights another target creature.
If that creature would die this turn, instead exile
it and put a number of +1/+1 counters on Predatory Amalgamation equal to the exiled creature's power.
