Lifelink is a static ability.

Damage dealt by a source with lifelink causes that source’s controller, or its owner if it has no controller, to gain that much life (in addition to any other results that damage causes). See rule 120.3.

If an object changes zones before an effect causes it to deal damage, its last known information is used to determine whether it had lifelink.

The lifelink rules function no matter what zone an object with lifelink deals damage from.

If multiple sources with lifelink deal damage at the same time, they cause separate life gain events (see rules 119.9–10).

Multiple instances of lifelink on the same object are redundant.

Living metal is a keyword ability found on some Vehicles. “Living metal” means “During your turn, this permanent is an artifact creature in addition to its other types.”

To convert a permanent, turn it so that its other face is up. This follows rules 701.28a–f, 712.9–10, and 712.18. Those rules apply to converting a permanent just as they apply to transforming a permanent.

Although converting a permanent uses the same physical action as turning a permanent face up or face down, they are different game actions. Abilities that trigger when a permanent is turned face down won’t trigger when that permanent converts, and so on.

If a spell or ability instructs a player to convert a permanent that isn’t represented by a transforming token or a transforming double-faced card, nothing happens.

If a spell or ability instructs a player to convert a permanent, and the face that permanent would convert into is represented by an instant or sorcery card face, or is a transforming token that was created with an instant or sorcery face, nothing happens.

If an activated or triggered ability of a permanent that isn’t a delayed triggered ability of that permanent tries to convert it, the permanent does so only if it hasn’t converted or transformed since the ability was put onto the stack. If a delayed triggered ability of a permanent tries to convert that permanent, the permanent does so only if it hasn’t converted or transformed since that delayed triggered ability was created. In both cases, if the permanent has already transformed or converted, an instruction to do either is ignored.

If a spell or ability states that a permanent can’t transform, that permanent also can’t convert.

More Than Meets the Eye represents a static ability that functions in any zone from which the spell may be cast. “More Than Meets the Eye [cost]” means “You may cast this card converted by paying [cost] rather than its mana cost.” Casting a spell using its More Than Meets the Eye ability follows the rules for paying alternative costs (see 601.2b and 601.2f–h). See rule 701.50, “Convert.”
