Two headed giant question

[Oldschoolmtgnoob]

How would you handle the ingest ability in a two headed giant game? Does each opponent exile a card from their deck, or just one, decided in some way?

[griffin131]

Any time an effect triggers off of combat damage to a player, you decide which opponent when the creature does damage.

If it has double strike, you can pick head A during first strike damage and B during normal damage.

You don't have to announce prior to that.

To complement Griffin's answer.

{benthic infiltrator} for reference on ingest.

The ruling below deals on the combat  damage step in 2HG.

810.7f: As the combat damage step begins, the active team announces how each attacking creature will assign its combat damage. If an attacking creature would assign combat damage to the defending team, the active team chooses only one of the defending players for that creature to assign its combat damage to. Then the defending team announces how each blocking creature will assign its combat damage. See rule 510.1.

Ergo: each unblocked attacking creature deals damage to one player only, even though the team shares life totals.

With double strike, you get two damage steps, so you could choose two different opponents.

Oh wow, so I really don't know how to play two headed giant. I thought you share life totals, so a specific oppenent would be a little ambiguous. What are the actual rules?

[Kaylesh]

The rules as included in the complementary rules can be found at section 810.
It being a casual format you can do houserules though. Once did shared hand/shared mana. I'd advise against that. Things based on cards in hand explode.

Condensed version, two players, one life total, one turn.

My playgroup has a house rule that you're considered one opponent so {Gray Merchant of Asphodel} effects aren't completely op.

[Oldschoolmtgnoob]

So we played it the right way I think; one turn per team, separate hands and mana pools, shared combat phases. What might be a recommended solution that doesn't seem too ridiculous? Another example: {ulamog, the ceaseless hunger}

Sorry...somehow I totally missed/forgot some of the answers. Absent seizure? I don't know

Thank you all the same
