I put "become enchantment" on Peculiar Chanting and then I realised the "and no longer creature" might not actually in white's pie, though it seems like it should be.

In many cases this is like blink, it saves your creature, or removes an opposing creature from combat. But it's also a bit like preventing damage. And will occasionally be different, eg. it avoids ETB effects, but might combo with enchantment effects.

Makes most auras (and all equipment) fall off, too. So seems very plausibly white in power - though more blue or maybe even red in flavour.
