Hi Ken! (Every time you summon a doll creature with
"Ken" in its name, put a +1/+1 counter this card)
Barbie gains +1/+1 for each legendary creature
you control that shares a unique type with it.
Whenever barbie attacks, for each other nontoken Barbie,
Ken, or Dream permanent on your field, create a
1/1 Human Doll creature token named Ken with
"Just Ken"
