Activate Goblin Bombardment by sacrificing another creature.
When the creature dies, Fleshtaker triggers, causing you to gain 1 life and scry 1.
Matoya triggers, causing you to draw a card.
The Locust God triggers, creating a 1/1 Insect creature token with flying and haste.
Resolve the Goblin Bombardment ability.
Repeat.
This loop starts by using Goblin Bombardment to sacrifice a creature, sending it to the graveyard and triggering Fleshtaker to scry 1. That scry immediately satisfies Matoya, Archon Elder, causing you to draw a card, which in turn feeds The Locust God's triggered ability to churn out a fresh 1/1 flying Insect token. Since that new token can be immediately sacrificed back to Goblin Bombardment to restart the cycle, Fleshtaker's lifegain and the enchantment's direct damage can be repeated as many times as you like.
