I like this. It's a good alternative to my suggestion of merging master of the past and Anomaly Sphere.

EDIT: I do think it's a bit expensive... Paying a total of 35 gems and 2 turns is a big price to pay for undoing one turn.

Even against Laputa/Gateway?

Thing is, if your opponent has enough resources to play Laputa on the turn he draws it, then this card won't do you any good. So the cost isn't just the extra gems, but also the fact that it doesn't work all the time because of timing.

Maybe you're right. I think I can add Quick keyword for this card.

Will it work after playing a Quick card?

It should be. These cards negate last round, not last turn.

I think it won't if it follows the same rules with Foundations.

exactly, master of the past and anomaly sphere don't work after a quick (since the data of opponent last card are deleted by your last quick action... I suppose). If you look at the code of those card you can see this line:
if (!($mylast_card->IsPlayAgainCard() and $mylast_action == 'play'))
that means that the following code works only if you have not played a playagain card (quick or swift)

Then just put the effect of Master Of the Past and Anomaly Sphere in this card in Modes and have it apply to opponent's last round, make the card rare and keep the cost as it is

Done.

I like this card. Did you mean to leave the Quick keyword in, though? Just saying since the original reason for making it Quick no longer applies.

Honestly I'm not sure about that. Maybe it should be but I should raise cost to 30 gems?
