Just to clarify, even if the creature has been under the other players control for more the turn it was summoned on, it will still have summoning sickness when you take control of it with volition reins?
Yes, Exsam already posted the rule.
302.6. A creature's activated ability with the tap symbol or the untap symbol in its activation cost can't be activated unless the creature has been under its controller's control continuously since his or her most recent turn began. A creature can't attack unless it has been under its controller's control continuously since his or her most recent turn began. This rule is informally called the "summoning sickness" rule
Other player's control is not the same as it's controller's control.
Also, what's the difference in protection from red and spells that read...'can't be prevented.' Ie, Combust. Thanks for the help.
Not sure if you're asking this or not, but Unstable Footing would work on Kor Firewalker as pointed out above. Combust would not because it is trying to target the firewalker, which protection prevents.
but if creatures has only been declared as blockers, and have not yet been assigned, is it possible to do this still? sorry if i keep on asking, just trying to make sure
Here you go:
509.1h An attacking creature with one or more creatures declared as blockers for it becomes a blocked creature; one with no creatures declared as blockers for it becomes an unblocked creature. This remains unchanged until the creature is removed from combat, an effect says that it becomes blocked or unblocked, or the combat phase ends, whichever comes first. A creature remains blocked even if all the creatures blocking it are removed from combat.
What happens if both players control a mimic vat, and both players want to exile a creature that just hit the graveyard, who gets priority if anyone?
Both mimic vat abilities trigger at the same time. The two mimic vat abilities are put onto the stack in active player, then nonactive player order. So the nonactive player's ability will resolve first.
Just to add to what SaschaW said. You probably heard this info in reference to Emrakul.
It gets by Emrakul, the Aeons Torn because Emrakul has protection from colored spells (the key word is spells). Oblivion Ring gets by this because it does not target when it is a spell, it's triggered ability targets when it becomes a permanent.
It would be different if it just had protection from all colors or just protection from white. Oblivion Ring would not be able to get by either of these two.
I don't think your getting it. When I do 3 damage to it, it's considered "lethal" damage, but it's not that the damage isn't dealt to it. Because damage IS STILL DEALT TO IT AND NOT PREVENTED ACCORDING TO ITS DEFINITION. The lethal damage isn't the 3 points of damage, it's the last point that would take for its toughness to go from 1 to 0. Since lethal damage is what doesn't effect it, not damage in general, the only logical scenario that seems to be derived from that definition is that its toughness can never go below 1 unless you give it -1/-1 (or -2/-2 whatever). Once again, the definition never states the damage dealt to it is prevented, just that if it's toughness WERE to go to 0, it doesn't. So does it's toughness just stay at 1 allowing me to play stabbing pain? Or is there some secret hidden definition that says damage dealt to indestructible creatures is prevented saying multiple judges are wrong and that Whither can't kill indestructible creatures?
I don't think you understand how damage is dealt/marked. Damage DOES NOT reduce toughness.
When you deal 3 damage to a 3/3. It is a 3/3 with 3 marked damage on it. It is NOT a 3/0. It is destroyed because it has lethal damage. (Lethal Damage is damage equal to or greater than the creature's toughness or any amount of Deathtouch damage)
When you deal 3 damage to a 3/3 indestructible. It is a 3/3 with 3 damage marked on it. It doesn't become a "3/1". It has lethal damage but it can't be destroyed, so it isn't.

No. It gets exiled and not sacrificed, therefore, it doesn't go to the graveyard.

You can't target a planeswalker directly because it is neither a creature or a player. Lightning Bolt says target creature or player.

Clone can only copy creatures. Planeswalkers are not creatures, barring any abilities/spells that makes them one.
