What happens if a player realizes after the match that they accidently left out one card after they sideborded and only had 59 in the deck for games 2 and 3.

Then they got really really lucky.

They should still inform a judge, but there won’t be any penalty as long as it wasn’t intentional cheating.

Once a game in a match is finished, the composition of the deck that existed for that game no longer exists and the player can’t receive any deck problem penalties because of that deck composition.

How do split cards interact with brain in the jar?

When Brain in a Jar’s activated ability resolves, you can cast an instant or sorcery card with CMC equal to the number of charge counters on BiaJ for free. How this works with Split Cards is as follows: You can choose a split card if either half has a CMC equal to the number of counters, then you can cast either half of that card for free, not just the half with the matching CMC.

For example, if the second counter is put onto Brain in a Jar as its ability resolves, you can choose to cast Boom//Bust from your hand without paying its mana cost. If you do, you can cast either Boom or Bust, since the ability of Brain in a Jar only cares that the card’s CMC matches the number of counters, and Boom//Bust has a CMC of 2 while also having a CMC of 6. If you cast Bust, the fact that it doesn’t have a CMC of 2 doesn’t matter since BiaJ no longer cares about CMC at that point.

Interestingly, Brain in a Jar allows you to cast split cards with Fuse from your hand fused, as long as the CMC of one of the halves matches the number of counters on BiaJ. This is possible because you’re casting the spell from your hand, allowing it to be fused, and that Fuse isn’t an alternate cost but rather a choice you can make to cast both halves of the spell instead of just one or the other. 

(If Fuse were an alternate cost, then it would clash with casting the spell for free as you can only pay one alternate cost to cast a spell, but it’s not, so it doesn’t.)

For example, if you put the second counter on BiaJ as its ability resolves, you can choose to cast Breaking//Entering from your hand and cast either Breaking, Entering, or both halves fused.

Is a player allowed to shuffle their library in between turns just because they are bored and want something to do while the opponent is going.

No.

Players are only allowed to shuffle their library as part of pre-game procedures or when a spell or abilities tells them to do so.

If I have a from beyond and another creature and my opponent controls a sheoldred at my upkeep can I stack it so that the from beyond resolves first and then the sac trigger happens?

No.

Because it’s your turn, you triggers will always go on the stack below your opponents’ triggers. There’s no way to make them stack otherwise.

If some one uses a kitchen drinks archangel of Thune combo to gain infinite life and have an infinite/infinite with life link and their opponent has an infinite creature combo and swings at them, they block with the angle, what is the result?

There’s no such thing as infinite in Magic. Players need to choose numbers for how many times they’re going to execute their combos.
