The Stack

If u read my post instans and sorceries go to graveyard when they resolve. 

What I think is happening though is the guy your playing against mana leaks you and you respond with something else and he mana leaks you again with the same
Carsl which shouldn't be possible if it hasn't resolved yet it would not have gone to the graveyard yet

Let's say I doom blade a creature my opponent responds by making the creature hexproof for the turn.  Can I respond by doom bladeing the creature again do to his spell still being on the stack?

Yes. You can still target it before his spell resolves.

The last spell casted always resolves first.

Helloooo i have a question about the leonin shikari/lightning greaves combo. A guy i know said that if he targets a creature with an instant spell and i equip the greaves onto the targeted creature he can cast another instant spell targeting another one of my creatures before the first equip resolves, effectively destroying the second targeted creature. My question is, if the leonin shikari now allows me to attach, rather than equip equipments, making them instants, i can likewise respond to his second spell by attaching them to the second creature. The equip cost of the greaves is 0 so i could infinitely activate this ability to respond to his spells, right?

Yes, you are right.  For as long as you can pay the cost () you can keep adding the equip ability to the stack.

Thank you!

One thing though is you cannot equip once there is something on the stack.  So if he targets your creature u cannot equip it until the instant resolves.  If u equip first and then he targets your creature in response while equip ability is on the stack then the instant would still resolve first

Sorry, Poof, but with Leonin Shikari on the field, Lunamoth can equip in response to a spell.

His first part of the message seems to imply that it wasn't on the field yet thats the part I'm referring to.  He says his second targeted creature would be killed because he can't re equip to save it but he wouldn't of been able to save the first one to begin with

I see.  Yes, I thought they had Shikari on the board the whole time.
So, no, you cannot use the "equip" ability other than your main phase with an empty stack ("sorcery speed").  There are spells and abilities that can attach as an instant, but not the general equip ability.

Nope, the shikari and the other creature are both already on the field as well as the lightning greaves. What the other guy was saying qa tht I couldn't equip right after he cast the destruction spell. As in I can't equip in response to something that was targetting my creature while the greaves were equipping another one.

Let's say my oppenent doom blades a creature I own, can I cast an instant card draw, draw my card (Wich for this argument will be unsummon). Can I then cast unsummon to save my creature?

Yes, you sure can! You can respond to the resolution of your card draw spell with another instant, like the unsummon that you drew, all while that doom blade sits patiently on the stack for its turn to resolve.

Nivmagus Elemental and guttersnipe on the field. If I cast any instant/sorcery does the 2 damage happen if I choose to exile it after casting it to gain the 2 1/1 counters?
