The Fullmetal Alchemist

You have no maximum hand size.
If another effect causes you to discard a card,
discard it, but you may put it on top of your
library instead of into your graveyard.
{u/r}{u/r}{u/r}{t}: Discard a card from your hand. Add {1} to your mana pool for each artifact you
control.
"You can't gain something, without giving something
in return."
Edward Elric
