Stockpiling Celebrant

In Commander, Stockpiling Celebrant occupies a clean niche in sacrifice synergy decks: it asks nothing beyond the sacrifice triggers you're already generating and hands back Treasures that accelerate your next big play. Competitive Commander tables are fast enough that the Celebrant's value is measured in whether those Treasures let you deploy a finisher a turn earlier — in dedicated Aristocrats builds it does, in slower goodstuff piles it doesn't earn its slot. In 60-card formats like Modern and Pioneer, sacrifice decks exist but are tight on slots and rarely need a three-mana creature that doesn't directly threaten the board; Stockpiling Celebrant is unlikely to make the cut there. Standard is the friendliest 60-card environment for it if a dedicated sacrifice shell is present. Pauper is legal but the format's sacrifice engines are lean and focused on cheaper pieces, so it sits on the fringe.
