Lazotep Plating

2019-05-03 Army is a new creature type. It's possible to control a nontoken Army (perhaps a creature with the changeling ability) and, through combinations of other cards, it's possible to control multiple Army tokens. When instructed to amass, you may put +1/+1 counters on any of your Army creatures, and you may choose a different one each time.
2019-05-03 If you create a Zombie Army token when Lazotep Plating instructs you to amass 1, that token will gain hexproof until end of turn.
2019-05-03 If you don't control an Army, the Zombie Army token that you create enters the battlefield as a 0/0 creature. Any abilities that trigger when a creature with a certain power enters the battlefield, such as that of Mentor of the Meek, will see the token enter as a 0/0 creature before it gets +1/+1 counters.
2019-05-03 You amass 1 and grant hexproof all while Lazotep Plating is resolving. Nothing can happen between the two, and no player may choose to take actions.
