Pyramid Song

How this card works

Pyramid Song costs 3 Eddies and offers two modes: give a rival Unit -5 power this turn, or bottom-deck a rival Unit with 0 power. If a friendly d4 is a min Gig, showing 1, you get both. A Unit with 5 or less power then drops to 0, since negative power counts as 0, and is bottom-decked by the second effect.

The FAQ confirms the order: top effect first, then bottom. To get the d4 down, the Spend on Wakako Okada: Peace and Harmony decreases a Gig by up to 2, and Trust No One decreases one by up to 3 for 1 Eddie, drawing a card if you then control a min Gig.

A d4 already at 1 cannot be lowered, because a Gig cannot be set to its current value. Bottom-decking skips the trash, so it does not trigger defeat effects.
