(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.)

Create two tapped
Powerstone tokens
(A Powerstone is an artifact with "
: Add
. This mana can't be spent to cast a nonartifact spell.").

Choose two target players. Until your next turn, each creature they control attacks the other chosen player each combat if able.

The Brothers' War deals X damage to any target and X damage to any other target, where X is the number of artifacts you control.
