A forecast ability is a special kind of activated ability that can be activated only from a player’s hand. It’s written “Forecast — [Activated ability].”

A forecast ability may be activated only during the upkeep step of the card’s owner and only once each turn. The controller of the forecast ability reveals the card with that ability from their hand as the ability is activated. That player plays with that card revealed in their hand until it leaves the player’s hand or until a step or phase that isn’t an upkeep step begins, whichever comes first.

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.”
