2 {Reverberate}s and a {Blistercoil Weird}

Cast both, each of the reverberates targeting each other.  With the blister of the field, infinite copies that would be cast, making blister power and toughness infinite/infinite

Nope sorry coils says cast you are only copying

[JustAWalrus]

Rule 601.2a look it up, a copy counts as casting a new spell on tge stack

What is your first reverberate copying? It had to have a valid target on the stack in order for you to cast it.

I don't believe you can set up an infinite loop playing this out. Besides its only two spells.

Also if you were able to make this an infinite loop (via some other way) the game would end in a draw as there would be no end.

Ok thanks!

Actually, Reverbate is an instant, so while it's going on, you can swing, for game if he gets first strike / trample.

Please stop spreading false information.

If a truely infinite loop is created it will draw the game as it will never resolve and move the game to the next phase.

Adding other elements into the equation also does not help and can cause confusion.

[Mlerner12]

Right. Cast them during combat, it's an instant, then you can attack with him an infinity/infinity. Or is there something I'm overlooking?

Possibly just the point that it doesnt work? They can't target themselves to create an infinite loop.

[Mlerner12]

Why not? You cast two, copy each other, get two more, repeat?

What do you target with the first reverberate? When you cast reverberate you need it to target a spell on the stack. According to the example, there is nothing on the stack.

[Mlerner12]

Right, missed that. Thanks! 😉

[Wally]

Also, in the example, there has only been two spells cast (three if there was a legal target for the first reverberate)

The blistercoil weird would only get a total of +3/+3 buff. copies are not cast, they are only copies.

[Mlerner12]

Well, if they were simultaneous, someone mentioned earlier that it counts in rulings.

See below

706.10.: To copy a spell or activated ability means to put a copy of it onto the stack; a copy of a spell isn't cast and a copy of an activated ability isn't activated. A copy of a spell or ability copies both the characteristics of the spell or ability and all decisions made for it, including modes, targets, the value of X, and additional or alternative costs. (See rule 601, "Casting Spells.") Choices that are normally made on resolution are not copied. If an effect of the copy refers to objects used to pay its costs, it uses the objects used to pay the costs of the original spell or ability. A copy of a spell is owned by the player under whose control it was put on the stack. A copy of a spell or ability is controlled by the player under whose control it was put on the stack. A copy of a spell is itself a spell, even though it has no spell card associated with it. A copy of an ability is itself an ability.
Example: A player casts Fork, targeting an Emerald Charm. Fork reads, "Copy target instant or sorcery spell, except that the copy is red. You may choose new targets for the copy." Emerald Charm is a green instant that reads, "Choose one -- Untap target permanent; or destroy target non-Aura enchantment; or target creature loses flying until end of turn." When the Fork resolves, it puts a copy of the Emerald Charm on the stack except the copy is red, not green. The copy has the same mode that was chosen for the original Emerald Charm. It does not necessarily have the same target, but only because Fork allows choosing of new targets.
Example: Fling is an instant that reads, "As an additional cost to cast Fling, sacrifice a creature" and "Fling deals damage equal to the sacrificed creature's power to target creature or player." When determining how much damage a copy of Fling deals, it checks the power of the creature sacrificed to pay for the original Fling.
