Jill, Shiva's Dominant // Shiva, Warden of Ice

When Jill enters, return up to one other target nonland permanent to its owner's hand. {3}{U}{U}, {T}: Exile Jill, then return it to the battlefield transformed under its owner's control. Activate only as a sorcery.

(As this Saga enters and after your draw step, add a lore counter.) I, II — Mesmerize — Target creature can't be blocked this turn. III — Cold Snap — Tap all lands your opponents control. Exile Shiva, then return it to the battlefield (front face up).
