Rules Tip of the Day: Several years ago a few cards were printed with the type 'Mana Source.' These cards all have errata so they are now instants. These spells will use the stack when played.

Q: If I play Pyromantics and pay an extra 3RRR (Replicating three times) and then use an Izzet Guildmage to make a copy of the original Pyromantics, will the copy contain 3 Replicated copies as well?

A: No. The Replicate triggered ability will only trigger when you play a spell. When this copy created by the Guildmage's ability goes on the stack it won't trigger the Replicate ability, and you won't get any additional Replicate copies from this spell.

Q: If I have Horobi, Death's Wail and I play Cry of Contrition, haunting my opponent's creature after they have discarded... what happens? Will the opponent's creature die from Horobi's trigger? If so, will the haunt mechanic of Cry of Contrition resolve, forcing them to discard again?

A: When the Cry of Contrition goes to the graveyard its Haunt ability will trigger. When this triggered ability goes on the stack you'll choose a target creature. This will trigger Horobi's ability, which will go on the stack on top of the Haunt ability. Horobi's ability will resolve first and destroy the targeted creature. At this point, the creature is not Haunted, so your opponent will not have to discard again. Then the Haunt ability will become countered on resolution, as its target is no longer legal.

Q: If I make a Blind Hunter token using Followed Footsteps, is there any opportunity for the token to Haunt something before it ceases to exist?

A: When this token creature goes to the graveyard, the Haunt ability will trigger, and you will choose a target for this ability as it goes on the stack. But when the ability resolves, the token will not exist any longer. So no, you won't be able to actually Haunt the targeted creature.

Q: I have an Aetherplasm enchanted with Entangler and my opponent attacks with five creatures. I use the Aetherplasm to block them all, and bring it back to my hand. Can I put in a blocker from my hand for each creature that attacked? If not, is the new blocker blocking all creatures or just one?

A: You'll only be able to put one creature card into play and it will only be blocking one of the attacking creatures. Aetherplasm's ability does trigger once for each creature it blocks. However, when one of these triggered abilities resolves, you are only able to put a creature card in your hand into play if you return Aetherplasm to your hand. So if you return the Aetherplasm to your hand when the first of these triggered abilities resolves, you will be able to put a creature card in your hand into play blocking one of those creatures. But when the other triggered abilities resolve, you won't be able to return the ®therplasm to your hand, so you can't put any additional creature cards in play. These other attacking creatures will remain blocked, but there will not be a creature blocking them.

Q: How is the ability of Blazing Archon correctly applied in a Two-Headed Giant game? Does it only keep opposing creatures from attacking the player that controls it or would it apply to both team members?

A: In a Two-Headed Giant game you attack the opposing team. You do not attack individual players on the opposing team. If there is a restriction that prevents a creature from attacking a single player on an opposing team, then that creature cannot attack that team. So if one player controls Blazing Archon, then that entire team cannot be attacked by creatures.

Q: I have Shared Fate in play and I have three opponents. This is in a four player free-for-all game. I cast Prosperity for ten. How does this resolve and who has access to the cards removed from my library?

A: Technically speaking, when Prosperity resolves each player will draw 10 cards at the same time. But because Shared Fate is in play, each player will end up having to deal with these draws in turn, starting with the active player. For each draw a player would make, he needs to choose a library controlled by an opponent and remove the top card from it. He would then continue doing this until he has dealt with all 10 draws. This process will then continue around the table in the same order that priority is passed until all four player have dealt with Prosperity's draws.

Finally, each individual player will have access to only those cards that he or she has removed from the game. So only player B will be able to play the cards he has removed from your library. You, player C, and Player D will not.

Q: In my hand are three Counterspells. If my opponent asks me "Do you have a Counterspell?" What am I within the rules to say and not say? Am I allowed to straight up lie, and say no?

A: Magic is not Go-fish. You are under no obligation to say anything. You also do not have to tell the truth if you do choose to respond. The simple fact is that the question by your opponent is not covered in the rules of Magic at all. Because of this your opponent cannot expect to get an answer of any kind, honest or otherwise, from you.

[Note that this does not apply to public information, like your life total, or the current power and toughness of a creature you control. Players must be honest when responding to questions about publicly available game state - Seamus]
