702.55. Replicate
702.55a Replicate is a keyword that represents two abilities. The first is a static ability that
functions while the spell with replicate is on the stack. The second is a triggered ability that
functions while the spell with replicate is on the stack. “Replicate [cost]” means “As an
additional cost to cast this spell, you may pay [cost] any number of times” and “When you cast
this spell, if a replicate cost was paid for it, copy it for each time its replicate cost was paid. If
the spell has any targets, you may choose new targets for any of the copies.” Paying a spell’s
replicate cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

706.2. When copying an object, the copy acquires the copiable values of the original object’s
characteristics and, for an object on the stack, choices made when casting or activating it (mode,
targets, the value of X, whether it was kicked, how it will affect multiple targets, and so on). The
“copiable values” are the values derived from the text printed on the object (that text being name,
mana cost, color indicator, card type, subtype, supertype, rules text, power, toughness, and/or
loyalty), as modified by other copy effects, by its face-down status, and by “as . . . enters the
battlefield” and “as . . . is turned face up” abilities that set power and toughness (and may also set
additional characteristics). Other effects (including type-changing and text-changing effects), status,
and counters are not copied.

117.8. Some spells and abilities have additional costs. An additional cost is a cost listed in a spell’s rules text, or applied to a spell or ability from another effect, that its controller must pay at the same time that player pays the spell’s mana cost or the ability’s activation cost. A cost is an additional cost only if it’s phrased using the word “additional.” Note that some additional costs are listed in keywords; see rule 702.

117.8d Additional costs don’t change a spell’s mana cost, only what its controller has to pay to cast it. Spells and abilities that ask for that spell’s mana cost still see the original value.

702.32a Kicker is a static ability that functions while the spell with kicker is on the stack. “Kicker [cost]” means “You may pay an additional [cost] as you cast this spell.” Paying a spell’s kicker cost(s) follows the rules for paying additional costs in rules 601.2b and 601.2f–h.
