Manticore Eternal
Creature — Zombie Manticore
Afflict 3 (Whenever this creature becomes blocked, defending player loses 3 life.)
Manticore Eternal attacks each combat if able.
While most Eternals were initiates who completed the trials, Bolas had plans for some of Amonkhet's other denizens.

Rulings
If, during your declare attackers step, Manticore Eternal is tapped or is affected by a spell or ability that says it can’t attack, then it doesn’t attack. If there’s a cost associated with having it attack, you aren’t forced to pay that cost, so it doesn’t have to attack in that case either.
If multiple creatures block a creature with afflict, afflict triggers only once.
Afflict causes the defending player to lose life; it’s not damage or combat damage.
If a creature is attacking a planeswalker, that planeswalker’s controller is the defending player.
Afflict resolves before combat damage is dealt. If this loss of life brings a player to 0 life or less, that player loses the game immediately. A blocking creature with lifelink won’t deal combat damage in time to save that player.
