When a creature is damaged and has critical life, PT turns to
red(critical life is 2 and below), if a card has a powered down status
like from -1/-1 counter, the PT turns to thistle, if powered up above 4,
the PT turns into yellow, default is white. legendary eldrazi pt is
violet. Token Indicator is T, and C for cards with copy abilities(so we
can differentiate them from originals), TC for both token and copy cat
cards.
