Esmeraude

Whenever an opponent discards a card, you may {b/g}{2}. If you do, return a target creature card from your graveyard to the battlefield, tapped.

{b/g}{b/g}{1}, {t}: Target player discards a card. If it's a land card, Esmeraude gets a +1/+1 counter.

Whenever Esmeraude deals combat damage to a player, that player discards a card, and you may draw a card.
