Spelltwine

[Mentonin]

If you choose the order u choose dispel then mercy. So mercy resolve first then dispel fizzle with no targets.

dispel does not fizzle, because it cannot be even cast without legal targets. The real question is: can you say you check dispel first (you won't be able to cast it), then cast the mercy, then not check if you are able to cast dispel again?

[Paraluke]

I should stop replying stuff for today, my brain is not working normally. Sorry, I actually wanted to say not caster (if anyone is to go by my replies earlier).

[MisterJH]

I feel like he cannot legally use spelltwine in this case without using a counterspell on the {angel's mercy}, but im no rules expert.. I jus seems like all the replies are pointing to it being illegal

[addoexatrum]

Being the caster of spelltwine he picks how the next two spells are put on the stack then as spelltwine says "cast them if able" if mercy is first on the stack it resolves first. Dispel has no target and is unable to cast so nothing happens.

[Double-O-Scotch]

I think the problem is that both copies go on the stack together as {spelltwine} resolves but you get to pick which goes off first. If the mercy goes off first, the dispel will counter hit the stack second with only one thing to target. That's my interpretation. I haven't seen a thread in such need of resolution since the {karona false god} - {control magic} thread. Where's the gavel of {gorzeyeto}???

Actually the caster of  {Spelltwine} chooses the order. Here are the full gatherer rulings:

7/1/2012   Spelltwine has two targets: the instant or sorcery card in your graveyard and the one in an opponent's graveyard. You can't cast Spelltwine unless you can choose both legal targets.
7/1/2012   If one of Spelltwine's targets is illegal when Spelltwine tries to resolve, you'll still exile and copy the remaining legal target.
7/1/2012   The copies are created in exile and cast from exile. The cards remain exiled.
7/1/2012   You can cast the copies in either order.
7/1/2012   The copy you cast first will already be on the stack when you cast the other copy. If that spell targets a spell, you may choose the first copy as a legal target.
7/1/2012   If you cast a card "without paying its mana cost," you can't pay any alternative costs. You can pay additional costs such as kicker costs. If the card has mandatory additional costs, you must pay those.
7/1/2012   If the card has X in its mana cost, you must choose 0 as its value.

[Mentonin]

Yeah, he chooses the order. But can he choose the counter to be placed first (thus not being able to cast for no targets) or will he need to cast the mercy first, since he isn't able to cast the counter, then cast the counter now that he is able?

I think he can play the counter and than play mercy.

The key question here is can he legally choose to cast the dispel first? The reason for that being Spelltwine states "cast the copies if able" the only legal way to satisfy that statement is to cast dispel second targeting mercy unless dispel can target itself.

[Jlamb5]

Based on the text, it seems that you must cast both if able. The only way to be able to cast the {dispel} is with a target and since the controller chooses which to cast first, in order to cast it fulfill the requirements of "cast the copies if able" text,  you must first cast the {angels mercy}.

I may be wrong, but with the rules written the way they are and the text bein pretty straight forward, I would play it this way, unless a judge told me otherwise.

This has gotten out of hand lol. What exactly are we disputing at this point?

Alright let me see if I can cover all of this, as far as this scenario goes.

First off, you can target the {Dispel} with {Spelltwine}. Nothing illegal about that. Nothing is being cast, just being targeted for exile.

THEN, the casting comes. You'll have to cast dispel second. It's simple, really. It says "cast them if able." You are not able to cast a counter spell without a valid target already on the stack.

You would have to cast the {Angel's Mercy} first, and then {Dispel}, targeting the Mercy.

Did that answer the remaining questions?

[The1337Magician]

Yep. Thanks Keyeto!

[Mentonin]

Can you target {spelltwine} for the {dispel}?

[Coffee Vampire]

You can't target spelltwine because it is already resolving. It is no longer on the stack.
