If an ability would produce one or more mana of an undefined type, it produces no mana instead.

Some abilities produce mana based on the type of mana another permanent or permanents “could produce.” The type of mana a permanent could produce at any time includes any type of mana that an ability of that permanent would produce if the ability were to resolve at that time, taking into account any applicable replacement effects in any possible order. Ignore whether any costs of the ability could or could not be paid. If that permanent wouldn’t produce any mana under these conditions, or no type of mana can be defined this way, there’s no type of mana it could produce.

To “tap [a permanent] for mana” is to activate a mana ability of that permanent that includes the {T} symbol in its activation cost. See rule 605, “Mana Abilities.”

An ability that triggers whenever a permanent “is tapped for mana” or is tapped for mana of a specified type triggers whenever such a mana ability resolves and produces mana or the specified type of mana.

A replacement effect that applies if a permanent “is tapped for mana” or tapped for mana of a specific type and/or amount modifies the mana production event while such an ability is resolving and producing mana or the specified type and/or amount of mana.

If an object’s enters-the-battlefield triggered ability or replacement effect refers to X, and the spell that became that object as it resolved had a value of X chosen for any of its costs, the value of X for that ability is the same as the value of X for that spell, although the value of X for that permanent is 0. This is an exception to rule 107.3i.

The tap symbol is {T}. The tap symbol in an activation cost means “Tap this permanent.” A permanent that’s already tapped can’t be tapped again to pay the cost. A creature’s activated ability with the tap symbol in its activation cost can’t be activated unless the creature has been under its controller’s control continuously since their most recent turn began. See rule 302.6.

The untap symbol is {Q}. The untap symbol in an activation cost means “Untap this permanent.” A permanent that’s already untapped can’t be untapped again to pay the cost. A creature’s activated ability with the untap symbol in its activation cost can’t be activated unless the creature has been under its controller’s control continuously since their most recent turn began. See rule 302.6.

Ogre Geargrabber’s control-changing effect ends during the cleanup step, at the same time that damage marked on permanents is removed. If you still controlled the Equipment at that time, this causes the delayed triggered ability to trigger. It goes on the stack and players can respond (which normally doesn’t happen during the cleanup step), then, once that cleanup step ends, another one begins.

Any ability of the targeted Equipment that triggers “whenever equipped creature attacks” won’t trigger. That’s because Ogre Geargrabber is already attacking at the time that Equipment becomes attached to it.

If the targeted Equipment can’t be attached to Ogre Geargrabber for some reason, you’ll still gain control of it until end of turn.

The delayed triggered ability (“When you lose control of that Equipment, unattach it”) triggers the next time you lose control of the Equipment for any reason, not just when Ogre Geargrabber’s control-changing effect ends. The Equipment will become unattached from whatever creature it happens to be attached to at that time. It doesn’t matter if Ogre Geargrabber is still on the battlefield at this time.
