Ghired, Conclave Exile
Legendary Creature — Human Shaman
When Ghired, Conclave Exile enters the battlefield, create a 4/4 green Rhino creature token with trample.
Whenever Ghired attacks, populate. The token enters the battlefield tapped and attacking. (To populate, create a token that's a copy of a creature token you control.)

Rulings
You choose which player or planeswalker the created token is attacking. It doesn’t have to be attacking the same player or planeswalker that Ghired is attacking.
Although the token is an attacking creature, it was never declared as an attacking creature. This means that abilities that trigger whenever a creature attacks won’t trigger when it enters the battlefield attacking.
Any effects that say that the token can’t attack (such as that of Doomed Artisan, or if you copy a token with defender) affect only the declaration of attackers. They won’t stop the token you populate from entering the battlefield attacking.
In some rare cases, you might copy a creature token that isn’t normally a creature. This token enters the battlefield as a noncreature permanent. It will be tapped but it won’t be attacking.
