reverberate and twincast

Asked by zigkid3 13 years ago

is it possible to some how make copies of a copy spell to make an infinite loop to have a tie game?

like if i cast Reverberate and choose to copy nothing to keep it the same, and then cast a second Reverberate to copy the first one, and then it keeps being allowed to recopy the first one over and over to have a tie game because of the infinite loop.

Your example can't be played out the way you describe, because you're not allowed to cast a spell that takes targets without naming enough legal targets for it, so you can't cast Reverberate copying nothing to start the chain.

The game only gets into a loop situation that ends in a draw if everyone suddenly gets stuck in a loop that's made entirely of mandatory actions. If it's possible for a player to break the loop by making a different choice somewhere along the way, then that player has to choose a number of times to repeat the loop, and then make that different choice to break the loop and let the game continue.

First, you cannot cast Reverberate without something to copy, and you cannot choose to copy nothing. Second, it won't create an infinite loop: You'll copy something twice no matter how you slice it.

You cannot create an infinite loop with Reverberate. I was in the process of describing how you could potentially do it, but then I stumbled across the 'may' in Reverberate's text that makes a true infinite impossible. Here's the proof for why you cannot do it: An instant or sorcery spell, 2 Reverberates/Twincast s, and a counterspell.

  1. First spell goes on the stack. Let's use Turn to Frog
  2. You cast Reverberate targeting Turn to Frog.
  3. Before Reverberate resolves, you cast Twincast , targeting Reverberate.
  4. Before Twincast resolves, you cast Cancel on Turn to Frog.
  5. Cancel resolves, putting Turn to Frog into its owner's graveyard.
  6. Twincast resolves, copying Reverberate. You may choose another spell to copy or leave the target of your copy alone: This copy will 'remember' that Turn to Frog existed, and if you let it resolve it will fizzle because its target no longer exists.
  7. Alternately, you can choose to have your copy of Reverberate target the original Reverberate. When this resolves, repeat 6: Choose to copy the original target for Reverberate, or change it to a new target.

This isn't a true infinite because the loop can be broken at any time by you simply making a different choice: You can choose to have the Twincast-cloned Reverberate copy the original Reverberate and make a loop, but you can break the loop at any time by simply not changing targets.

go look up the Time Warp /Time Walk with Call to Mind decks. I think that this is the closest way to get what you are trying to get at
