Can I block an incoming attack with Creature and the flash in Glorious Protector and miss the damage? or does the Protector take the hit?
You can and this is a very common use of the card. Similarly you can block and then sacrifice the creature to say Village Rites and the damage will still be blocked. The only time this isn't the case is if they have trample.
A source is anything that exists in magic so you can just say anything. Elvish Mystic is the source of G, Grapeshot is the source of its trigger. Squire isn't a source except yes it is because equip it with Viridian Longbow and its now a source and it always has been because if a source is anything with the potential to be a source then it is.
Yeah it works. And there's not really a concept of one stack. This all happens in a single step (the declare attackers step) but once a spell or ability has resolved both players get an opportunity to cast/activate new things and anything that triggers from the previous item resolving will trigger. So in your case:
Empty Stack
Zur attack trigger
both players can respond
Animate dead enters and triggers declaring a target
Both players can respond
Animate dead resolves and Oracle enters the battlefield triggering
Both players can respond
You would have to cast Tainted Pact here before Oracle resolves
Both players can respond again
Pact resolves
Both players can respond
Oracle resolves.
Unless specifically stated it is public compare to Blufferfish.
On a more general note it is public because when you activate the ability you must choose a target which your opponent will know about and be able to respond to.
You can change their positions in order to clarify the board, but you cannot do so in order to confuse your opponent. If you have multiple face down cards and your opponent asks which one is the face down card they know about you would have to tell them.
The combat phase has 5 steps with the last one being the End of Combat step. While in that step creatures are still considered attacking/blocking even though damage has already been dealt so they still work with cards like Brazen Cannonade or Maze of Ith, but once you leave that step and enter Main phase two all creatures are no longer considered attacking/blocking.
Once a block has been declared the creature will remain blocked until end of combat no matter what happens to the blocker. You would need to kill the creature before blocks are declared.
When Sepulchral Primordial enters the battlefield there are two triggers, the primordial and the artisan. When two triggers are put on to the stack at the same time they are put there with the Active player's on the bottom and the non active players on the top to resolve first so if this a normal casting of Primordial on the opponent's turn then they will put their trigger on the stack with the target chosen and then your trigger from artisan will go on top of that. Then Artisan will resolve and create a token of Primordial which will trigger and you will choose up to one creature to reanimate. Your token primordial will resolve its trigger to bring something back (which may or may not cause additional triggers) before finally the original Primordial's trigger resolves.
If you both chose the same target (keep in mind that it has to be an opponent's graveyard so this is only possible in multiplayer) then your opponents trigger will fizzle because the target is no longer there. This can also happen if you were to bring back say Scavenging Ooze and eat the original target before it resolves.
Next up: what the heck this does when it copies equipment, especially equipment with Living Weapon.
Creatures cannot equip something so if you activate its equip ability it will just fail. Same thing with living weapon. The token is created, this tries to attach, but fails and the token dies as a 0/0.
I like that it has things going for it whether you draw it early or late. On turn one you can grow it each turn and if you draw it late game it's generally at least a deathtouch blocker. I can't think of a way yet, but if there's an easy/cheap way to get artifacts in to play on the opponents turn as well this could be really strong rather than just solid.

Oh.
So that's why they banned it. Can't make new mythics less fun.
