The "Recover" mechanic

[Shatterhouse]

Cards with "Recover (cost)" let you return them from your graveyard to your hand when one of your creatures is put into your graveyard from the battlefield, if you pay the cost. You only get one chance. If you don't pay it, the card is exiled. It shouldn't trigger if an opponent's creature goes to the graveyard, and it shouldn't trigger if your creature wound up there from anywhere else(i.e. via discarding or counterspell)

Here's how you make a card with this ability(Icefall is the example):

Code: Select all

<TRIGGERED_ABILITY tag="ICEFALL_RULE2" zone="Graveyard" layer="0" auto_skip="1">
 <TRIGGER value="HIT_GRAVEYARD">
        return  ((TriggerObject():GetCardType():Test(CARD_TYPE_CREATURE) ~= 0) and (TriggerObject():GetErstwhileZone() == ZONE_IN_PLAY) and (TriggerObject():GetPlayer() == Object():GetPlayer() ) and (Object():GetZone() == ZONE_GRAVEYARD))
 </TRIGGER>
<COST qualifier="Conditional" type="Mana" cost="{R}{R}" />
   <EFFECT>
     Object():PutInHand()
     Object():GuidedReveal( ZONE_GRAVEYARD, ZONE_HAND )
   </EFFECT>
   <ELSE_EFFECT>
     Object():RemoveFromGame()
   </ELSE_EFFECT>
</TRIGGERED_ABILITY>
