Q: If I have a Leonin Abunas and a Bosh, Iron Golem in play, does that mean I can't equip Bosh with anything?

A: Reread Leonin Abunas. It says that your artifacts can't be the target of spells or abilities your opponents control. Therefore you may equip Bosh.

Q: When Oath of Scholars is in play, do I need to chose a target opponent and stick with the chosen one, or do I select an opponent during each upkeep?

A: Oath of Scholars is no longer targeted. Here's the latest wording:

At the beginning of each player's upkeep, if that player has fewer cards in hand than any of his or her opponents, the player may discard his or her hand and draw three cards.

In a multiplayer game, so long as any opponent has more cards than you, the Oath will trigger. It will also check on resolution to make sure the condition is true.

Q: Will tapping a Mesmeric Orb with an Icy Manipulator turn off its ability?

A: No, because it doesn't say so on the card.

Q: Can I use Future Sight with Parallel Thoughts to see the top of both"libraries" before drawing ?

A: The cards under the Parallel Thoughts aren't a library, therefore you cannot.

Q: If I have Sacred Ground out and my opponent casts Akroma's Vengeance what happens?

A: Your Sacred Ground will be destroyed along with all the other enchantments. It won't trigger because you aren't putting any lands in the graveyard. If you happened to have artifact lands in play, Sacred Ground will trigger for each of them because it sees them go to the graveyard at the same time that it does. You'll put them all back into play.

Q: If I turn a Quicksilver Elemental face down by copying and using a Mischievous Quanar's ability, can I ever turn it face up again? Is it treated like a normal morph in the meantime?

A: The Elemental becomes a 2/2 creature with no abilities (rule 502.26e). Because Morph isn't an activated ability, that ability is not copied, and the Quanar'd Elemental can't turn itself face up (it doesn't have Morph.) You could still use Break Open or Ixidor to turn the creature face up.

Q: I have a Gratuitous Violence in play and I attack with a 5/5, can my opponent Stifle the double damage? I think not, but if he can, do I deal five or nothing?

A: You're correct; your opponent can't Stifle the double damage - it's a replacement effect, not an activated or triggered ability. Unlike in the olden days, replacement of combat damage is still combat damage.

Q: Can I imprint Interrupts on Isochron Scepter, or enchantments I can play as instants?

A: What used to be Interrupts are now Instants, so yes, you can Imprint them. Non-instants that can be played when you could play Instants aren't Instants, so no.

Q: I have a Auriok Bladewarden 1/1 (Mirrodin) in play and tap him to give an other creature of mine"+X/+X where X is the Auriok Bladewarden's power." My friends plays Terror in response, targeting the Auriok Bladewarden. So the stack first handles the Terror and kills the Auriok Bladewarden. Then the stack gets to the"+X/+X" ability of the (now deceased) Auriok Bladewarden.

My friend says now the ability looks back to see the Auriok Bladewarden's power. Because it isn't alive its power is zero and so the ability gives my other creature just +0/+0. I say it still gives the creature +1/+1. Who is right?

A: The ability looks on resolution for the Bladewarden's power. If a spell or ability needs to know information about a permanent that's no longer in play, it takes the information as it existed just before it left. We call this"last known information." If the Bladewarden's power was 1 when it was Terrored, then it gives +1/+1.

Q: Can Artifacts be regenerated? For example, the Loxodon Mender's ability is Regenerate target artifact. My friend says you can only regenerate creatures, so it can only be artifact creatures. Is this right?

A: You are correct. Regeneration doesn't just apply to creatures. It's an effect that can replace any destruction event.

Q: I have a Seasinger in play. My opponent controls no Islands, but I use Mystic Compass to change one of his lands to an Island and then use Seasinger's ability to gain control of one of his creatures. Will I keep control of that creature after the end of turn when my opponent controls no Islands again?

A: You'll keep control of the creature. The opponent controlling an Island is only a targeting restriction. Once you gain control of the creature, you'll keep it until you lose control of the Seasinger or the Seasinger becomes tapped.

Q: Is Null Rod the same as Damping Matrix? I'm asking this because of their wording. Damping Matrix specifically says that mana abilities can still be used. So if I have a Null Rod in play, can my opponent or I still tap artifact lands for mana?

A: They are not the same. Null Rod prevents all activated artifact abilities, to include mana abilities.

Q: If a Chalice of the Void is set to one counter (was cast for two mana) and my opponent has a Chatter of the Squirrel in the graveyard (one mana cost). The flash back cost is 1G. When the spell is cast with the flashback cost, is the spells converted mana cost 1 or 2? I.E. Is it canceled by the Chalice?

A: The converted mana cost of a Flashback spell is the cost of the spell, not the Flashback cost. Chatter of the Squirrel, played normally or via Flashback, will be countered by a Chalice with 1 counter on it.

Q: Why would Erratic Explosion deal four damage when you reveal Fire / Ice (converted mana cost = 4), but then you can also imprint Fire/Ice on an Isochron Scepter? Isn't the converted mana cost still four? Or do you have the choice of using 1)one side or 2)both when a spell or effect asks for the converted mana cost?

A: Effects that ask for a particular characteristic of a split card while it's in a zone other than the stack get an answer that consists of a combination of the split card's two halves (rule 505.5). Effects that ask if a split card's characteristic (in any zone other than the stack) matches a given value get only one answer. This answer is"yes" if either side of the split card matches the given value (rule 505.6).

Here are two examples, straight from the rulebook:

Example 1: Infernal Genesis has an ability that reads,"At the beginning of each player's upkeep, that player puts the top card from his or her library into his or her graveyard. He or she then puts X 1/1 black Minion creature tokens into play, where X is that card's converted mana cost." If the top card of your library is Assault / Battery when this ability resolves, you get five 1/1 creature tokens because Assault's converted mana cost is one and Battery's is four, for a total of five.

Example 2: Void reads,"Choose a number. Destroy all artifacts and creatures with converted mana cost equal to that number. Then target player reveals his or her hand and discards from it all nonland cards with converted mana cost equal to the number." If a player plays Void and chooses one or four, his or her opponent would discard Assault/Battery. If the player chooses five, Assault/Battery would be unaffected, because neither half has a converted mana cost of five.

Q: I have a question in regard to how Clockwork creatures work in relation to +1/+1 counters they did not generate. Say my Clockwork Condor has run out of all +1/+1 counters originally placed on it, but has three +1/+1 counters from Wurmskin Forger. I had assumed that +1/+1 counters placed on it by another source didn't cause the ability to activate and cause a +1/+1 to be removed, but on Magic Online, I still lost a counter. Is this a bug on Magic Online or is this really how the ability works?

A: All +1/+1 counters are created equal (rule 200.10). It doesn't matter how they got there. Treat them just like the originals. This time, it's not a bug in Magic Online.

Q: If there are multiple Worldslayers in play and an equipped creature deals combat damage, do all Worldslayers stay in play, or just the one that was equipping the attacking creature? What if two attacking creatures are thus equipped and deal damage?

A: Just the one that was equipping the attacking creature stays in play. If two attacking creatures are Worldslayer-equipped, then each will destroy the other (in addition to everything else).

When a card refers to itself by name, it means only that specific version of the card.
