Questions on +/- Counters?

[Black_to_Red]

I have some questions about spells that give creatures a + or - number, counters etc.

Question 1) If the negative number goes against the creatures toughness and is enough to... (kill it, destroy it, cause it to go the graveyard, etc), when does it resolve?

Question 2) Does the negative counter destroy the creature? Is it similar to combat damage?

Question 3) When does the creature have to leave play (instantly, EOT, etc.) ?

Question 4) Can creatures that go to the graveyard, because of this effect, be regenerated?

Question 5) Does the effect last the entire turn?  


Thanks

These questions belong in the rules forum.

If a creatures toughness is ever reduced to zero or less, it will die as a state-based effect. The next time any player would receive priority, the creature is put into its owner's graveyard. It is not destroyed. An indestructible creature with a toughness of zero is put into the graveyard, too. Because this is not a destruction effect, but rather a state-based effect, the creature cannot be regenerated. The -1 effect lasts as long as it says it will. If the spell/effect says that a creature gets -1/-1 until the end of turn, the effect wears off during the Cleanup step. If it's a -1/-1 counter, it lasts as long as the counter remains on the creature.

Thanks Ephraim.  I had a feeling that was the answer.  I was looking for a Clergy of the Holy Nimbus/Skullclamp draw engine.  Oh well, back to the drawing board.

Also note that Regenerated creatures never leave play, so won't trigger Skullclamp.
