Faldorn, Wolves' Fang

If you would exile a card from your library,
instead exile that card with a [xyz] counter on it.
Whenever you cast a spell from exile or a land
enters the battlefield under your control from
exile, create a 2/2 green Wolf creature token.
{r}{g/u},{t}: You may play target card you own from
exile with a [xyz] counter on it this turn. Activate
this ability only during your turn.
