Circi, The Lady of Luxury

Defender: {t} Sacrifice {3} Life: Claim 1 basic land from any of your opponents and place a 1/1 counter on Circi. The land card becomes any colour under your control. Once a counter is added to Circi she gains the ability to attack.
"Just when you get comfortable Circi senses your warm spot and unapologetically claims it as her own."
