Josephine, The Antiquarian

Virtuous (If you have 10 or more stress counters
when you gain a Curio artifact token, you may
draw a card)
When Antiquarian enters the battlefield, you
may draw a card. If you do, discard a card
{t}: Add {w} or {u}. Spend this mana only to cast artifact or enchantment spells.
Here Death! I knock at your door!
