Rules Tip of the Day: Unless specified, an activated ability can be played as many times as it can be paid for.

Q: Can you use Sins of the Past to play Suspend spells without mana costs?

A: Yes, you can. You cannot normally play a card without a mana cost, but if an effect allows you to play this card without paying its mana cost, you can play it.

Q: If I have a single Call of the Herd in my graveyard, is the Flashback cost reduced by Locket of Yesterdays?

A: No. When you play a spell, the first thing that happens is that the card representing the spell goes on the stack. Later in the announcement process, you determine the cost of this spell. At this point, you will not have any copies of Call of the Herd in your graveyard, so Locket of Yesterdays will not lower the Flashback cost.

Q: Can I put Mangara of Corondor's his ability on the stack; respond by untapping him with Twiddle or Freed from the Real; then tap him again, targeting another permanent?

A: Yes, that works. Removing Mangara of Corondor from the game is part of the effect from this ability, not a cost. If you do untap Mangara in some way, then you will be able to remove more than one permanent.

Q: Does Harmonic Sliver destroy a artifact or enchantment when it comes into play?

A: Yes. Harmonic Sliver's static ability applies to itself, even when it is a resolving spell. It will come into play with this triggered ability.

Q: When Ixidron comes into play, and creatures are turned face-down, do they retain their abilities?

A: No. Face-down creatures do not have any abilities.

Q: I have in play a Mishra, Artificer Prodigy, and during my upkeep I remove the last time counter on my Lotus Bloom and play it. Will this let me go through my library, hand, or graveyard and bring another Lotus Bloom into play without playing it for it's Suspend cost?

A: Yes. When Mishra's ability resolves, you can search for a copy of the artifact spell that triggered Mishra's ability and put it into play. Doing so does not count as playing this card, so you can put this card with a non-existent mana cost directly into play.

Q: If my Mindleech Mass does damage to a player I get to play a non-land card from their hand. Since I am playing a card from my opponent's hand, does that mean any card that reads "only play on an opponent", such as Betrayal, apply to the opponents of the player whose hand I am playing from?

A: No. You are the controller of this spell, so any reference to an opponent means your opponent. It does not matter who the owner of the card is.

Q: Will Price of Glory trigger if I use Piracy to tap my opponent's land for mana during my turn?

A: No. Price of Glory's ability triggers when the non-active player taps a land for mana. You may be tapping the lands controlled by the non-active player for mana, but you are still the active player.

Q: How does Children of Korlis work in Two-Headed Giant games? Is it different from from situations involving Darien, King of Kjeldor or Circles of Protection?

A: The ability from Children of Korlis only 'counts' the life lost by an the one player. Teammates may share a life total in Two-Headed Giant, but that does not mean that when one player takes damage or loses life that the other player does as well. This situation is very similar to the Two-Headed Giant interactions with King Darien and the Circles of Protection. When you assign damage to a player, only that player will receive damage and then lose life equal to that amount of damage. The loss of life is then applied to the shared life total of the team.
