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.

The subtype Shapeshifter that appears on the type line is mostly there to reinforce the flavor. A creature card with changeling is just as much an Elf, a Dwarf, a Sliver, a Goat, a Coward, and a Zombie as it is a Shapeshifter.

For the second triggered ability, you can choose any permanent as the target, regardless of who controls it.

If the permanent being copied is itself a token, the token created by the last ability copies the original characteristics of that token as stated by the effect that created it.

For the first triggered ability, the instant or sorcery spell can target other things if it also targets one or more permanents you control; however, the token you create can copy only permanents you control that are targets of the spell. If the spell targets more than one permanent you control, you choose which permanent the token is copying as you create the token.

Changeling is a characteristic-defining ability. It functions in all zones, not only while a card that has it is on the battlefield.

If the permanent being copied has {X} in its mana cost, X is 0.

If an effect causes a creature with changeling to become a new creature type, it will be only that new creature type. It will still have changeling; the effect making it all creature types will simply be overwritten.

The token copies exactly what is printed on the permanent and nothing else (unless that permanent is a token or is copying something else; see below). It doesn’t copy whether that permanent is tapped or untapped, whether it has any counters on it, whether it has any Auras and/or Equipment attached to it, or any non-copy effects that changed its power, toughness, types, color, and so on.

Orvar’s first triggered ability resolves (if it resolves; see below) before the spell or ability that caused it to trigger.

Any enters-the-battlefield abilities of the copied permanent will trigger when the token enters the battlefield. Any “As [this permanent] enters the battlefield” or “[This permanent] enters the battlefield with” abilities of the copied permanent will also work.

If a spell or ability an opponent controls allows or instructs you to choose a card to discard, and you discard Orvar, its last ability will trigger.

If the spell itself has left the stack by that point, use the targets it had when it left the stack to perform the check described above.

If an effect causes a creature with changeling to lose all abilities, it will remain all creature types, even though it will no longer have changeling. This is because changeling applies before the effect that removes it.

If the permanent being copied is copying something else, the token you create will use the copiable values of the that permanent. In most cases, it will be a copy of whatever the permanent is copying. If it’s copying a permanent or card with {X} in its mana cost, X is 0.

As the first triggered ability tries to resolve, the spell that caused it to trigger and that spell’s targets are checked again. Ignore any target of the spell that has left the battlefield by that point. If all of the permanents you controlled that were targets have left the battlefield by that point, the triggered ability will do nothing and no token will be created. If at least one permanent you control that’s a target is still on the battlefield, the triggered ability will resolve, even if that permanent is now an illegal target for the spell.
