Backup is a triggered ability. “Backup N” means “When this creature enters, put N +1/+1 counters on target creature. If that’s another creature, it also gains the non-backup abilities of this creature printed below this one until end of turn.” Cards with backup have one or more abilities printed after the backup ability. (Some cards with backup also have abilities printed before the backup ability.)

If a permanent enters the battlefield as a copy of a permanent with a backup ability or a token is created that is a copy of that permanent, the order of abilities printed on it is maintained.

Only abilities printed on the object with backup are granted by its backup ability. Any abilities gained by a permanent, whether due to a copy effect, an effect that grants an ability to a permanent, or an effect that creates a token with certain abilities, are not granted by a backup ability.

The abilities that a backup ability grants are determined as the ability is put on the stack. They won’t change if the permanent with backup loses any abilities after the ability is put on the stack but before it resolves.

Menace is an evasion ability.

A creature with menace can’t be blocked except by two or more creatures. (See rule 509, “Declare Blockers Step.”)

Multiple instances of menace on the same creature are redundant.

Cycling is an activated ability that functions only while the card with cycling is in a player’s hand. “Cycling [cost]” means “[Cost], Discard this card: Draw a card.”

Although the cycling ability can be activated only if the card is in a player’s hand, it continues to exist while the object is on the battlefield and in all other zones. Therefore objects with cycling will be affected by effects that depend on objects having one or more activated abilities.

Some cards with cycling have abilities that trigger when they’re cycled. “When you cycle this card” means “When you discard this card to pay an activation cost of a cycling ability.” These abilities trigger from whatever zone the card winds up in after it’s cycled.

Some cards have abilities that trigger whenever a player “cycles or discards” a card. These abilities trigger only once when a card is cycled.

Typecycling is a variant of the cycling ability. “[Type]cycling [cost]” means “[Cost], Discard this card: Search your library for a [type] card, reveal it, and put it into your hand. Then shuffle your library.” This type is usually a subtype (as in “mountaincycling”) but can be any card type, subtype, supertype, or combination thereof (as in “basic landcycling”).

Typecycling abilities are cycling abilities, and typecycling costs are cycling costs. Any cards that trigger when a player cycles a card will trigger when a card is discarded to pay an activation cost of a typecycling ability. Any effect that stops players from cycling cards will stop players from activating cards’ typecycling abilities. Any effect that increases or reduces a cycling cost will increase or reduce a typecycling cost. Any effect that looks for a card with cycling will find a card with typecycling.
