Sparky, Great Mechamancer

Spells you cast that target Cat creatures you
control have Replicate {x} where X is equal to
the spells converted mana cost minus {2}. You
can only pay this replicate cost once, and it must
target Sparky, Mechacat.
Whenever a red mana source is tapped for mana,
Sparky, Mechacat gets +1/+0 until end of turn.
