Rulings:

• 11/10/2020 Both triggered abilities trigger at the same time. You may put them on the stack in either order.
• 11/10/2020 If the opponent doesn’t control more creatures than you as their end step begins, the first ability won’t trigger. The same is true for lands and the second ability. Each of those abilities will check again when it tries to resolve. If the opponent no longer controls more creatures (or lands) than you, the ability won’t resolve and will have no effect.
