If I attached an equipment or enchantment sandbar crocodile would they go in the graveyard when sandbar phases (I've always had trouble understanding phasing)
When a permanent phases out, any permanents attached to that first permanent (e.g. auras or equipment) also phase out. They remain attached to the phased out permanent and will phase back in when it does.
This is known as indirect phasing.
The attached permanent is reliant on the enchanted/equipped permanent, however, and will only phase in again if and when it does. This interaction is sometimes hilariously abused in Legacy by using Sapphire Charm or other similar cards to phase out an opponent’s Germ token along with the Batterskull that’s equipped to it. A phased out token ceases to exist when state-based actions are checked, and since the token no longer exists, there’s no way for Batterskull to ever phase back in. It’s stuck in phased-out limbo for the rest of the game.
