Dódeka Áetoi, the Golden Crab

Whenever Dodeka Áetoi enters the battlefield or attacks, create a Treasure token.
{2}, {t}: Create a 0/4 colorless Wall artifact
creature token with defender. If mana from a
Treasure was spent to activate this ability, you
may instead search your library for a basic land
card, put it onto the battlefield tapped, then
shuffle.
Whenever Dodeka Áetoi or another Crab dies,
that creature's controller creates a 1/1 green and
white Citizen creature token.
