We know how this works by now- there's been a few threads on it. What I'd like to know is do the rules allow shortcuts on multiple coin flips? Basically, what I want to do is roll a d4 with both in play, 1 being two losses, 2 and 3 being loss and a win, and 4 being two wins.
If yes, can I do similar with Krark's Thumb in play as well and a d8?
It's not allowed to shortcut an arbitrary number of coin flips or die rolls:
C.R. 726.2a: A declared shortcut must have a sequence of choices with "predictable results"; moreover, the shortcut "can't include conditional actions".
M.T.R. 4.4: In a sanctioned tournament, "[n]on-deterministic loops ([including] loops that rely on ... probability ...) may not be shortcut".
However, you can roll fair dice in a way that substitutes for coin flips, as long as "all players agree to the substitution" (C.R. 705.3). More generally, the players can agree to any "metho[d] of randomization" that achieves the same purpose of flipping multiple coins, as long as "there are two possible outcomes of equal likelihood" for each coin flip modeled this way (C.R. 705.3). A similar rule exists for die rolls (C.R. 706.1b).
The number isn't arbitrary though. It's four or eight and it's not a loop.
Edit: okay I can probably concede the predictable part. Although part of me thinks what conditional actions exactly could happen in the middle of figuring out how spells are added to the stack and resolve
Son of edit: so maybe agreement can get past most of that?

Yes. If it's just a fixed and small number of coin flips, you can roll multiple fair dice to achieve the same result as flipping multiple coins, as long as all the players in the game agree (C.R. 705.3). There are other, potentially faster, ways to randomize that the players could agree on.
