Glieria Warlord

Avarice (Whenever this creature deals combat
damage to a player, you may exile target card from
your graveyard with converted mana cost less than
this creature's power. Until end of turn, you may play
that card.)
Whenever Glieria Warlord attacks, you may
discard a card. If you do, search your library for a
card that shares a card type with the discarded
card, reveal it, put it into your hand, then shuffle
your library.
