Duke Ulder Ravengard

Each token copies exactly what was printed on the original creature and nothing else. It doesn’t copy whether that creature is tapped or untapped, whether it has any counters on it or Auras and Equipment attached to it, or any non-copy effects that have changed its power, toughness, types, color, and so on.

The tokens all enter the battlefield at the same time.

If the defending player is your only opponent, no tokens are put onto the battlefield.

Any enters-the-battlefield abilities of the copied creature will trigger when the tokens enter the battlefield. Any “as [this permanent] enters the battlefield” or “[this permanent] enters the battlefield with” abilities of the copied creature will also work.

If myriad creates more than one token for any given player (due to an effect such as the one Doubling Season creates), you may choose separately for each token whether it’s attacking the player or a planeswalker they control.

You choose whether each token is attacking the player or a planeswalker they control as the token is created. If it’s attacking a planeswalker, you choose which one.
