 * The token will copy Pack Rat's two abilities. Its power and toughness will be
 * equal to the number of Rats you control (not the number of Rats you
 * controlled when the token entered the battlefield). It will also be able to
 * create copies of itself.
 *
 * The token won't copy counters on Pack Rat, nor will it copy other effects
 * that have changed Pack Rat's power, toughness, types, color, or so on.
 * Normally, this means the token will simply be a Pack Rat. But if any copy
 * effects have affected that Pack Rat, they're taken into account.
 *
 * If Pack Rat leaves the battlefield before its activated ability resolves, the
 * token will still enter the battlefield as a copy of Pack Rat, using Pack
 * Rat's copiable values from when it was last on the battlefield.
