Urza Assembles the Titans

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 — Scry 4, then you may reveal the top card of your library. If a planeswalker card is revealed this way, put it into your hand.

II — You may put a planeswalker card with mana value 6 or less from your hand onto the battlefield.

III — You may activate the loyalty abilities of planeswalkers you control twice this turn rather than only once.
