As an example, consider the ability of Momochi, Elite Ninja of Gales:

Put 1 of your other SIGNI on the field into the trash: Until end of turn, 1 of your opponent's SIGNI gets −2000 power for each level of the SIGNI put into the trash this way.

The stuff before the colon—the part that tells you to put 1 of your other SIGNI into the trash—is the cost. The stuff after the colon—the power-decreasing part—is the effect.

Azazela's ability will only activate if you put her into the trash as part of an effect. Therefore putting her into the trash to pay the cost of Momochi's ability will not cause you to draw a card.

While costs won't trigger Azazela's ability, everything else is an effect, and thus fair game. For example, putting Azazela into the trash for the ability of Hockeymask, the 13th Friday will let you draw a card. Trashing Azazela for your own Bloody Slash will also draw you a card—even though the banish part of Bloody Slash is dependent on you trashing one of your own SIGNI, the SIGNI-trashing part is not behind a colon, so it's considered to be an effect, and thus will trigger Azazela.
