The only problem is, you can play a ton of these all at once, and then your opponent is left with an empty hand and a larger deck. Any thoughts as how to correct this, anyone?
My suggestion, they draw one card and shuffle a different one back. Hand destruction isn't always a favored card.
Remember that when you play one of these, your hand shrinks by one card too. If you play four or five at once, you and your opponent will both be left with empty hands.
Drawing a replacement card would actually potentially be in favor of the opponent, it'd be like adding an Hourglass effect on top of the card's effect. Thanks for the input, but this isn't a direction I'm going to go.
This effect is less useful than rewind by itself (they will not have to pay quanta twice) however this card gains more synergy with itself than multiple rewinds do. I think that it currently has a balanced cost.
I think changing it to shuffle target player's hand into their deck and then they draw an equal number of cards would work as an alternative.
I see the card as similar to Discord or Mutation - it's a mixed bag. You could "rewind" something devastating, or you could actually help your opponent (say, if he wants to Fractal and you just reshuffled a pillar or something). It would actually be most useful in non-mono decks, say something like
with Mindgate or
Elf/Druid-stall.
In fact I just thought of a very neat synergy:
. Use Procrastination and you can actually plan out your Dispersions to have a better chance of reshuffling a critical card! These days most people use Procrastination to shrink their deck ideas to "24 cards," this would give a bit more usefulness to the espionage aspect.
