Etb Token

Creatures whose ETB trigger generates one or more creature tokens, making them prime flicker targets for repeatable token production. Avenger of Zendikar floods the board with Plants scaled to lands, Grave Titan churns out Zombies, Myr Battlesphere drops four Myr alongside its body, and Hornet Queen leaves behind a swarm of flying deathtouch Insects. Distinct from flicker.etb_value, which covers ETB card-draw and ramp bodies, and from flicker.etb_damage and flicker.etb_removal, which trigger drains or kill effects on entry. Token creation on attack or upkeep is out of scope; only the ETB-on-a-creature trigger qualifies here.
