Whenever Brimaz, King of Oreskos attacks, create a 1/1 white Cat Soldier creature token with vigilance that's attacking.
Whenever Brimaz blocks a creature, create a 1/1 white Cat Soldier creature token with vigilance that's blocking that creature.
2/1/2014 For the first triggered ability, you declare which player or planeswalker the token is attacking as you put it onto the battlefield. It doesn’t have to be the same player or planeswalker Brimaz is attacking.
2/1/2014 If Brimaz somehow blocks two or more creatures (note it can’t naturally do this), its last ability will trigger that many times.
2/1/2014 Although the tokens enter the battlefield attacking or blocking, they were never declared as attacking or blocking creatures. Abilities that trigger whenever a creature attacks or blocks won’t trigger.
