Pizza Face, Gastromancer

If the target permanent has station, its base power and toughness will be set to 0/0. Adding charge counters to that permanent won't restore the power and toughness printed in any of its striations.

Food is an artifact type. Even though it appears on some creatures, it's never a creature type.

Whatever you do, don't eat the cards. (Also, don't make the pizzas pictured on the cards. You don't have the digestive system of a Ninja Turtle.)

If the target permanent is a Vehicle, its base power and toughness will be set to 0/0. Crewing that Vehicle will not restore its power and toughness.

Pizza Face's second ability doesn't remove any abilities the target permanent has.

The resulting creature will be able to attack on your turn if it's been under your control continuously since the turn began. That is, it doesn't matter how long it's been a creature, just how long it's been on the battlefield.

Some disappear abilities, such as those of the above cards, are triggered abilities with intervening if clauses. If a permanent hasn't left the battlefield under your control that turn by the time the disappear ability would trigger, it won't trigger at all.
