If you create a token that's a copy of Anax, its last ability triggers when it dies.

Mana symbols in the text boxes of permanents you control don't count toward your devotion to any color.

The ability that defines Anax's power works in all zones, not just the battlefield.

If Anax dies at the same time as another nontoken creature you control, its ability triggers for each of them.

If you put an Aura on an opponent's permanent, you still control the Aura, and mana symbols in its mana cost count towards your devotion.

If an activated ability or triggered ability has an effect that depends on your devotion to a color, you count the number of mana symbols of that color among the mana costs of permanents you control as the ability resolves. The permanent with that ability will be counted if it's still on the battlefield at that time.

Colorless and generic mana symbols (, , , , , and so on) in mana costs of permanents you control don't count toward your devotion to any color.

To determine whether you create two tokens, check the power of the creature that died immediately before it died.

Hybrid mana symbols, monocolored hybrid mana symbols, and Phyrexian mana symbols do count toward your devotion to their color(s).
