Tricorder

To “surveil N” means to look at the top N cards of your library, then put any number of them into your graveyard and the rest on top of your library in any order.

If an effect allows you to look at additional cards while you surveil, those cards are included among the cards you may put into your graveyard and on top of your library in any order.

If a player is instructed to surveil 0, no surveil event occurs. Abilities that trigger whenever a player surveils won’t trigger.

An ability that triggers whenever a player surveils triggers after the process described in rule 701.42a is complete, even if some or all of those actions were impossible.

Equip is an activated ability of Equipment cards. “Equip [cost]” means “[Cost]: Attach this permanent to target creature you control. Activate only as a sorcery.”

For more information about Equipment, see rule 301, “Artifacts.”

Equip abilities may further restrict what creatures may be chosen as legal targets. Such restrictions usually appear in the form “Equip [quality]” or “Equip [quality] creature.” These equip abilities may legally target only a creature that’s controlled by the player activating the ability and that has the chosen quality. Additional restrictions for an equip ability don’t restrict what the Equipment may be attached to.

If a permanent has multiple equip abilities, any of its equip abilities may be activated.

“Equip planeswalker” is a variant of the equip ability. “Equip planeswalker [cost]” means “[Cost]: Attach this permanent to target planeswalker you control as though that planeswalker were a creature. Activate only as a sorcery.”
