If I have the ability to shuffle my deck at will, and am able to look at the top card of my deck in-between each of the shuffles, would it be legal to short cut it to looking through my deck, selecting a card from it, shuffling the rest of my deck, and putting the selected card on top of it?
Theoretically, if I can shuffle any number of times, the card I want would eventually end up as the top card of the deck. But this could potentially take a very large number of shuffles and a very long time, especially in a 100 card deck with only one copy of the desired card. So I was wondering if I could just propose the short cut of just finding the card, shuffling the rest of the library, and putting the card on top.
While there are probably multiple scenarios for this to happen, my set up for it is: two Myr Galvanizer, enough myr mana dorks (ie Alloy Myr) to produce 3 mana, a Myr Mindservant, and a Mystic Forge.
Use two mana from the Myr Dorks to pay for and activate the shuffle ability of the Mindservant. Use the Forge's ability to look at the top card of my library, if it's not the desired card, use the remaining 1 mana from the dorks to pay for and activate the ability of a Galvanizer, untapping the dorks, the Mindservant and the other Galvanizer. Repeat until top card of library is desired card.
