Everything Time Vault

Just double checking, if you chose to legitimately untap time vault, do you do it between turns, or do you actually start your turn?

Well the errata states that if you would begin the turn with it tapped you may untap it and skip that turn, so technically it begins your turn before an untap step happens.

This is wrong.  the "If you would begin..." clause in Time Vault is a replacement effect, which replaces you beginning your turn with untapping Time Vault.  You therefore never begin the turn, just as if you replace a draw effect with another effect, you never draw a card.


Just out of curiousity, for what interactions is this relevant?

Oracle text: Time Vault enters the battlefield tapped.
Time Vault doesn't untap during your untap step.
If you would begin your turn while Time Vault is tapped, you may skip that turn instead. If you do, untap Time Vault.
Tap: Take an extra turn after this one.

It's moreso because Time Vault happens to be relitively good against Smokestack, but also things like Mindslaver.

My bad, I just suck at explaining shit, but ya it is good when facing down an opposing smoke stack for example.

If you go to time and "5 additional Turns" if a player skips a turn with by untapping time vault instead, that action doesn't take up one of the 5 turns.  (but taking extra turns does consume a turn).  So that could be relevant.

Also, the opponent cannot respond to it, so if they ended their turn with untapped mana planning to use it on your turn, you can instead use Time Vault to return it right back to their Untap Step without an opportunity for them to play anything.  It can give you a bit of tempo in the control mirror.
