My question is what you mean by 'human involvement'. For example: if there is a card that says to add a specific token to a specific place, with no choices, does everything that happens after the card is triggered count as human involvement? Or if the card says to shuffle the library, does the shuffling count as human involvement?

If your answer is no, then I think the current cards are already sufficient, it just needs some clever finagling to take the current design and remove all 'may' choices.

If your answer is yes then I think your standards are flawed.

Okay, looking into it it was less of a loop than I thought: http://www.mtgvault.com/doompie/decks/the-deck-ripper/
