Challenge Mode Ambuscade

Which is actually less difficult that requiring all 4 shuffle cards in the trash at the same time.

Not that it isn't incredibly rare, but there are ways it can happen.  The key is all devices need to be accounted for by being in the trash, in play or played by traps mid-chain for any of them to happen.  The 4 shuffle cards have to be dealt with, but they don't have to start in the trash, but even if they were all in the trash to start, you don't have a loop until the devices are dealt with, which mid-loop should be harder to get rid of.

The odds are still really, really low, and then only for a non-balanced challenge mode.

 

Which can be simplified to: remove 10 specific cards from his deck and play 1 of 2 cards remaining in his 15 card deck, and INEVITABLY play the other traps in his deck over and over until death or other infinite cycles.

Yes, it's difficult to pull off. We know. But it's there.

It's an unbalanced play mode used to up the challenge. Even though it could happen, I'm not sold that this is a huge deal all things considered

By getting rid of the line I made, you no longer have Quick Stim Patch and Run and Gun accounted for. By not factoring them in, you have now opened up the door to when one of the traps are on top of the deck, that when it reshuffles and places a card, that it plays one of those two cards, this will reshuffle the trash back into the deck, bringing all devices back with it. 

Oh okay. Well, it would be easier to pull it off by somehow discarding those four reshuffles before they were played then.

I wouldn't say most challenges are unbalanced, but this one seems to be particularly so just because he's Ambuscade.

Which probably lands at percentages lower even than the Megalopolis + Citizen Dawn combo that gives you no cards in hand to start, and then Traffic Pileup ends your game when you have no card play or damage base powers.
