DESCRIPTION
spawning shell {g} {3} (card text): ({pg} can be paid with either {g} or 2 life.)
{pg}, t, sacrifice a creature: search your library for a creature card with converted mana cost equal to the sacrificed creatures converted mana cost plus one, put that card onto the battlefield, then shuffle your library. activate this ability only anytime you could cast a sorcery.
the combo is simple. turn 1 you play either arbor elf, llanowar elf or bird of paradise. turn 2 you play spawning shell and sacrifice the creature to bring out myr sire. you sac that to play chieftain and sac the token to bring out another one mana guy and start over. at the end you will have at least 4 chieftains which is 20 damage. good game on turn 2.
