Reezug and Tinybones

Whenever one or more players discard one or
more creature cards, you may exile one of them
from its owner's graveyard. If you do, create a
token that's a copy of that card, except it's an
artifact and loses all other card types. This ability triggers only once each turn.
{x}{b}{b}{b}: Each player discards X cards, then
each player with no cards in hand draws seven
cards and loses 7 life.
