Titia, Secluded Disciple

X is 0+ the number of creatures you control.
If Titia deals or is dealt damage you may draw 2.
If you do, look at the top 3 cards of your library,
put them back in any order and choose one: scry
4 or mill 4, then you may lose 3 life to deal 5
damage to one target. If you do, choose one: pay
3 life to put an Ikari counter on Titia (at any time
you may remove this counter to counter target spell) or target player mills 2, discards 2 and loses 2 life.
