Does the same principle apply to a creature you have taken control of with Nicol Bolas, Planewsalker, that is, does Nicol Bolas, Planeswalker have to be/stay on the battlefield to keep control of the creature or is that a different situation?
Unless stated otherwise, any ability granted to creatures by another creature (e.g. by Gemhide Sliver, Constricting Sliver, etc.) cease to exist when the creature granting those abilities leaves play, correct?
If Portcullis is in play and destroyed, any creatures that were exiled under it are moved onto the battlefield from another zone so their ETB's would go off correct?
If I tap Path of Ancestry to cast a creature that shares a type with my commander (allowing me to scry 1) and when that creature enters the battlefield it also triggers my Kindred Discovery, do these triggers (one a cast trigger and one an ETB trigger) happen at the same time thus allowing me to stack them the way I want (i.e. so I can scry with Path of Ancestry before drawing a card from Kindred Discovery)?
If I have Eye of Singularity in play as well as Thespian's Stage, I can use Thespian's Stage each turn (for two mana) and destroy one of my opponent's non basic lands by copying them?
If my opponent has Grave Pact in play and two of his creatures are killed, can I sacrifice Reassembling Skeleton, bring it back, and sacrifice it again to satisfy Grave Pact?
One of the Gatherer Ruling says "If Mirage Mirror becomes a creature the same turn it enters the battlefield, you can’t attack with it or use any of its Tap abilities (if it gains any) unless it has haste." Does the first instance of the word "it" refer to Mirage Mirror or the creature?
So for example, if I play Mirage Mirror and on the same turn have it copy a creature that does not have summoning sickness, does the Mirage Mirror copy have summoning sickness? Or does the Mirage Mirror copy have summoning sickness when it copies a creature with summoning sickness?
Will Heartstone reduce the cost of creature abilities that specify colorless mana like Endbringer or does it only reduce GENERIC mana in creature abiliites?
Kjeldoran Outpost works differently than fetch lands (e.g. Flooded Strand) in that you can't sacrifice a Plains and then play Kjeldoran Outpost from your hand if you've already played a land during your turn, is that correct?
If I have Portcullis in play and there are two creatures on the battlefield and I bring in a creature with a non-ETB, non-tap ability, for example Sakura-Tribe Elder, is the creature able to activate it's ability before it is exiled under Portcullis?
If False Prophet (and the rest of the creatures on the battlefield) are destroyed by a board wipe such as Wrath of God or Nevinyrral's Disk does False Prophet's ability trigger before the other creatures hit the graveyard thereby removing them from the game?
Colorless mana is not "many of any color" so if Kozilek, the Great Distortion is your commander, even though it has colorless mana in its color identity, Command Tower would not produce colorless mana since it's restricted to colored mana production, is that correct?
So for example, if I play Mirage Mirror and on the same turn have it copy a creature that does not have summoning sickness, does the Mirage Mirror copy have summoning sickness? Or does the Mirage Mirror copy have summoning sickness when it copies a creature with summoning sickness?
