I'd never use this card.Too situational. It's SHC (Self Hand Control).Forces me to purge my hand of cards.
is there a difference between 'cast' and 'play'? is it automatic?No real difference - The restriction is only in the hand, so PU/Mitosis'll work regardless of hand conditioncan there be other dawnbringers in your hand when you play this?or are you pretty much screwed if you draw 2? (you'd need to discard and then play 7 cards..)No, because then it wouldn't be the only card in your hand. You're pretty much screwed.Do you get a benefit if your name is dawn to dusk?Yes.
If you're always sanctified, do you still get quanta from pillars?
