As this enchantment enters, choose Mardu or Jeskai. • Mardu — If a creature attacking causes a triggered ability of a permanent you control to trigger, that ability triggers an additional time. • Jeskai — At the beginning of your upkeep, create a 1/1 red Goblin creature token. It gains lifelink (Damage dealt by the creature also causes its controller to gain that much life.) and haste (This creature can attack, and as soon as it comes under your control.) until end of turn.
