Rona, Herald of Invasion - Synergies

Construct is the cleanest cheap discard payoff to check with Rona.

Mox Amber is the cleanest mana check for the deck, but it has demand across many legendary shells.

Cauldron is powerful here, but it already has other Commander and combo demand.

Cauldron lets Rona borrow creature abilities from exile. It already has demand elsewhere, so compare versions before crediting Rona alone.

The One Ring is a broad staple check, useful context but not a Rona-only card.
