In the situation where a game of 2HG is drawn (In KTK/FRF if Arcbond kills both teams), are the teams permitted to sideboard before game 2?

Reading the MTR, my initial opinion is that players would be allowed to sideboard, (MTR 9.6 Cards not used in a team’s starting decks are considered a shared sideboard by the two players that both players
can access.)

Additionally, can cards which began the first game in Player A's deck begin the second game in Player B's deck? Would this answer change if the TO wanted to hold the event at Comp REL? Currently you can swap cards between players at Regular in Team Sealed between matches but not games, but I am unsure if this would follow for 2HG Sealed since all cards are still being played in the same game.

Two Headed Giant can only be run at Regular REL. At Regular REL unless stated by the Head Judge continues deck construction is in effect so the teams can change the composition of their deck when they like

Gareth, what's your source that 2HG can only be at Regular?

MTR 9.5

Sideboards are not allowed in constructed Two-Headed Giant tournaments.

For sealed, should be ok.

I don't believe there is an official source as it's not official. They
have removed the support for 2HG from the Comp REL policies (try and
find mention of match point penalties now)

But unofficially anyone would be mad to try 2HG at Comp REL*. There
was a large experiment with it and a PT and such, the consensus is
that it just doesn't work, because games are slower it makes for a bad
player experience.


PS: I know I'm not the Gareth you asked the question of.

*Okay WotC weren't mad to try it, but it's been tried now, learn from
others mistakes.
