Ranas, Backstreet Gambler

Haste
{t}: Choose odd or even. Then, target opponent reveals the bottom card of their library and puts
it into their hand. If that card's converted mana
cost is even and you chose even or if that card's
converted mana cost is odd and you chose odd,
draw two cards and untap Ranas. (Zero is even.) Otherwise, draw a card, then discard a card.
