Mantle of Tides

In Commander, Mantle of Tides belongs exclusively in decks built around drawing multiple cards per turn, where the free-equip trigger fires consistently and the +1/+2 buff matters on a specific threat. In Pauper it competes in Heroic and aura-based strategies where cheap enchantments have more universal value, but the conditional equip clause makes it weaker than straightforward pump auras unless the deck is already running a second-draw engine. Modern and Legacy have no meaningful home for it — the effect is too small and too slow for those formats, and the restriction means it often sits as a dead aura for a full turn. Mantle of Tides is a narrow build-around piece that rewards the right shell generously and does almost nothing in the wrong one.
