The number of Zombies you control is counted when the ability resolves. If you control multiple Endless Ranks of the Dead, the tokens you get when the first ability resolves will count for the subsequent abilities (if the tokens are still under your control at that time).
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
