Read Ahead (Choose a chapter and start with that many lore counters. Add one after your draw step. Skipped chapters don't trigger. Sacrifice after III.)

I - Create a 0/2 colorless Thopter artifact creature token with flying named Ornithopter.

II - Tap any number of untapped artifacts you control. When you do, Yotia Declares War deals that much damage to target creature or planeswalker.

III - Up to one target artifact you control becomes a creature with power and toughness 4/4 until end of turn.
