My friends and I have a regular MTG-drafting group. It's pretty informal, and after we draft sometimes a group of 4 people will play Two-Headed-Giant just for fun since it's not really a tournament and more just a way to get together and play. However, several of them want to play the entire 'tournament' as all THG matches the next time we play. I have no problem with this at all and understand how THG works, but I'm curious as to the best way to do this in a draft.
Assuming we pick teams before the drafting, do we allow players to collaborate in choosing their cards? It seems like this would take way too long and require far too much effort to make the decks work well together. Granted, the effort would make for better decks for each team, but I don't think the extra time is worth it. I suggested that we not allow anyone to help their partner make decisions during the draft so they are still building a deck that can stand on its own, and not having one player run 23 counterspells and removals while the other runs 23 creatures. However, my friends say this could easily result in decks that do not play well together at all.
After we've picked the cards I figure everyone would be allowed to collaborate with their teammate to build their decks, but doing so during the draft just seems like too much. Currently I think players should not be allowed to give the cards they picked to their partner for their deck.
What limits should we impose on collaboration during the draft to allow the teams to build decks that synergize well, without drastically increasing the time requirement of the draft? Perhaps a 3-minute interval between each booster? How can we find a good balance of collaboration and increased time requirements?
