Omen of Dissension

(As this Saga enters and after your draw step, add
a lore counter. Sacrifice after IV.)
I, II, III—Each player sacrifices a creature or planeswalker. Each opponent who can't loses 4
life or discards a nonland card.
IV— Gain control of all noncreature artifacts
and enchantments with mana value X or less,
where X is the number of lore counters on Omen
of Dissension. Untap those permanents.
