I control Humble Defector.
My opponent controls Phyrexian Obliterator.
I cast Soul's Fire, have my defector deal 2 damage to Obliterator.
Obliterator triggers, as a response, I activate my defector, my opponent gains control of defector.
Who will sacrifice permanents for Obliterator?
Now to activate the mana ability of Wall of Root,
I need to pay the cost "Put a -0/-1 counter on Wall of Roots and pay {3}",
by the moment to pay the {3},
May I again activate the mana ability of Wall of Root?
(Why? Maybe I want it dead to fill my graveyard.)
I know there's "Activate only once each turn."
But the Activation is not finished before the costs are paid.
Technically I haven't yet activate the first activation...
I control a manifested shock and a Gathan Raiders.
I cast Mirrorweave, each creatures becomes a copy of Gathan Raiders.
Can I pay shock's morph cost(copied from Gathan Raiders)? (C.R. 702.37e)
I know it won't turn face up. (C.R. 701.34f)
So it remains face down that I can pay its morph cost again and again until hellbent.
What happens if I activate the ability with X=2 targeting Lazav in my graveyard?
Is its name Lazav, the Multifarious or Necrotic Ooze?
How many activated abilities would it have?
In response, I cast Hallow, targeting Snapdax on the stack.
Snapdax resolves, it becomes part of the meld permanent. Its ability triggers, which targets my Grizzly Bears.
Would Snapdax's trigger damage be prevented?

1. Cast Sword of the Realms - Back side of Halvar, God of Battle from my graveyard.

I play Lotus Vale from my graveyard.
I don't have two untapped lands sacrificed. So Lotus Vale goes to my graveyard from my graveyard.
My question is: Would Lotus Vale becomes a new object in my graveyard? Would it move to the top of my graveyard?
I know answer is yes if I exile some card in exile, rule 406.7.

I control Kardur, Doomscourge and Blood Vassal.
I attack with the Vassal, sacrifice itself to pay {2}.
Does Vassal dying triggers Kardur?
I know if there is a Dress Down on the battlefield, the Ruffian would enter the battlefield not transformed.
What if I have a Immerwolf, which have been Artificial Evolution changing "Human" by "Jellyfish".
Would the Ruffian, which is a non-Jellyfish Werewolf, enters the battlefield transformed?
Would the ability of the tomb trigger?
Sure that the ability of Crusher triggers because it saw the Tomb entered the battlefield.
My question is, would the ability of Tomb trigger? Did the Tomb see the Crusher left the graveyard?
I cast Metamorphic Alteration to lurker, make it a copy of itself.
What happens when it becomes day?
