Field of Reality
Evasion that only works against one creature type is a strange thing to build a card around, and this is what happens when a set leans hard enough into a tribe to make it worth doing. Spirits dominated the era this card comes from, so an aura that turns off Spirit blockers reads less like a generic combat tool and more like a narrow answer printed for a specific table: if the board you face is full of fliers and ground bodies wearing the Spirit creature type, this slides an attacker straight through. The bounce ability is the part that elevates it past a do-nothing-against-the-wrong-deck aura. For one and a blue, you pick the enchantment back up, which means it dodges spot removal aimed at the creature and reattaches to a fresh threat. That recursion is what keeps a hyper-conditional effect from being a complete blank: you commit it when the matchup rewards it and tuck it away when it doesn't. The trouble is that the floor stays low no matter how clever the bounce is, because the entire premise depends on the opponent's creature types cooperating. Outside a metagame saturated with one tribe, the text does nothing, and no amount of flexibility fixes an evasion clause that simply doesn't read most boards.
