Yotia Declares War (Dominaria United)

Enchantment Ñ Saga - 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 Ñ Create a 0/2 colorless Thopter artifact creature token with flying named Ornithopter.
II Ñ Tap any number of untapped artifacts you control. When you do, this Saga deals that much damage to target creature or planeswalker.
III Ñ Up to one target artifact you control becomes an artifact creature with base power and toughness 4/4 until end of turn.
