Elven Artifact

When Elven Artifact enters the battlefield, all Elves you control get +5/+5 until end of turn and gain trample and protection from Black.
If an Elf would die, instead, exile the elf with 3 Elven counters on it. Return the card to the battlefield tapped when there is no more counters on it.
When an elf deals combat damage to a player, you may resurrect an elf from your graveyard. It comes back with a -1/-1 counter on it for each time it has been resurrected.
