2 rulings from Wizards of the Coast
- 22 September 2011If you control fewer than two Zombies, you won't get any tokens.
- 22 September 2011The 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).
