So I've been told that Zombie Master's effect is that the discard is a cost to activate the effect, and then you proceed to target. This means that you could discard a zombie then summon it directly after the discard.
I've also been told that you need to set a target first, then discard, but this would go against the card text itself:
Once per turn: You can send 1 Monster Card from your hand to the Graveyard, then target 1 Level 4 or lower Zombie-Type monster in either player's Graveyard; Special Summon that target.
I just want to try and verify which one is true, and i cannot find any updated rulings. The only one I was able to find on the subject was from when Upper Deck still had control. --- http://img37.imageshack.us/img37/4632/morningrescue.gif
If you have no zombies in your grave or opponents grave, you can't activate it. If you do, you can send a zombie in your hand and bring back the sent one. It's a cost. --- PSN: OpTic_hnz KD-1.57 only snipe, don't judge.
^So, It works like Lumina, Lightsworn Summoner, right? --- Never refer to me by the letters in my username. It's an account name I had during my early school days that stuck. It does not sound too good when pronounced.
