Wax-Wane Witness is a free body stapled to a day/night toggle — the moment it enters, it forces a day-to-night or night-to-day shift without requiring you to do nothing on the previous turn, which is exactly the cheat Zoraline, Cosmos Caller needs to keep transforming cards on demand. At one white mana for a 1/1 that warps the day/night clock, the cost is negligible; the effect is the whole point.

Zoraline, Cosmos Caller
Zoraline, Cosmos Caller's engine lives and dies by reliable day/night transitions, and Wax-Wane Witness provides one on-demand the instant it hits the battlefield — no waiting on spell counts, no relying on opponents to cooperate, just an immediate clock flip that keeps every Daybound and Nightbound permanent in your deck cycling at full speed.
Format Analysis
Where it lives, where it can’t
| Format | Verdict |

Wax-Wane Witness is legal everywhere but sees virtually no play outside Commander, where the day/night mechanic exists in enough density to make the triggered ability meaningful. In competitive formats like Modern and Legacy, day/night matters only if you're running a dedicated Werewolf shell, and even there the 1/1 body doesn't clear the power bar. In Standard, the card is technically playable in a transforming-creatures deck but faces stiff competition for one-drops that do more on board. Commander is its home — specifically any deck where Zoraline, Cosmos Caller or a critical mass of Daybound and Nightbound permanents makes every forced transition worth a card slot.

Price Context
Current price
$0.08 bulk tier
At $0.08, Wax-Wane Witness is deep bulk — the kind of card you pull from a common box, not a store page. Given that its home is almost entirely Zoraline, Cosmos Caller Commander decks, demand is narrow enough that the price is unlikely to move unless Zoraline spikes in popularity.
