Krosis, Loyalty Undying

When Krosis enters the battlefield from your hand, create a 0/2 dragon egg card with "When this card is destroyed, create a 3/2 red dragon token with flying."
{b}{1}: Deal 3 damage to target player or Planeswalker. If you control Alduin, World Eater, this costs {1} less and deals 1 more damage.
"Unending Sorrow, in the Thu'um, is actually Krosis."
