Trample
Whenever a source deals damage to Rona, that source's controller exiles a card from their hand at random. If it's a land card, you may put it onto the battlefield under your control. Otherwise, you may cast it without paying its mana cost.
Picked for what they do in Rona's deck. When two cards do the same job, the one with the lower comes first. All of them fit Rona's color identity.Mana ValueThe total amount of mana a card costs, all added up. A card costing two generic and one green has a mana value of three. Wizards renamed this from "converted mana cost" in 2021, so older cards and articles may still use the old name.Open the full glossary

Most rulings are written by Wizards of the Coast, the company that makes Magic, and a few are notes from Scryfall, the card database Magic players use. A ruling explains a card. It does not change what the card says.Open the full glossary

If the spell has {X} in its mana cost, you must choose 0 as the value of X when casting it without paying its mana cost.
Wizards of the Coast14 Apr 2023
If you cast a spell without paying its mana cost, you can’t choose to cast it for any alternative costs. You can, however, pay any additional costs. If the spell has any mandatory additional costs, you must pay those.

Playing a legendary land won’t cause the first ability to trigger.

The first ability of Rona, Herald of Invasion will resolve before the spell that caused it to trigger.

The spell you cast from exile without paying its mana cost is cast during the resolution of the triggered ability. Timing restrictions of that spell based on card type are ignored.
Color identityEvery color of mana symbol on a card, in its cost and in its rules text. Your commander's color identity sets the limit for your whole deck: every other card has to fit inside it. A deck led by a green and white commander cannot play a card with any blue in its color identity.Open the full glossaryUBPlayers write colors as letters: U for blue, B for black. Blue is U because B was already taken by black.Madness/DiscardDiscard decks throw away their own cards on purpose and play cards that reward each discard. Cards with madness can even be cast for a different, usually cheaper, cost at the moment you discard them.Open the Madness/Discard pageOpponent DiscardMakes opponents discard cards from their hands. In a format where everyone starts with seven and refills slowly, stripping a hand can be harder to recover from than losing a creature. Windfall, Sword of Feast and FamineOpen the Opponent Discard pageLootingDraws and discards in the same breath. Faithless Looting, Frantic Search. It does not gain you cards. It improves the ones you have, and fills your graveyard on purpose, which is exactly what a reanimator card like Animate Dead wants.Open the Looting pageSelf-DiscardDiscards your own cards as a cost or an effect. Filling your own graveyard on purpose is the point: it feeds cards that bring things back, madness and channel abilities, and some cards are worth more there than in hand. Faithless Looting, Boseiju, Who EnduresOpen the Self-Discard pageLegends MatterLegends decks fill up on legendary cards and use cards that reward you each time you cast one. A legendary card has the word Legendary on its type line; you can only keep one with the same name in play, and nearly every commander is legendary.Open the Legends Matter pageHistoric PayoffRewards you for historic cards: the legendary cards, artifacts, and Sagas that Magic groups under that one word. In Commander your commander is always legendary, so these start with something to count. Jhoira, Weatherlight CaptainOpen the Historic Payoff pageChaosChaos decks fill the game with random effects like coin flips, dice rolls and random swaps, so nobody's plan goes as expected. It is built for fun and big stories more than for winning quickly.Open the Chaos pageCoin Flip / Die RollLeaves part of the outcome to chance: a coin flip, a die roll, or a choice made at random. A flip that can only hurt you, like the one on Mana Crypt, does not count, because no deck is built around it.

More cards means more choices every turn, and in a 100-card deck it is the main way to find the pieces you need. Rhystic Study, SkullclampOpen the Draw pageMana SinkGives you somewhere useful to spend spare mana, usually through an ability you can activate again and again. Rogue's Passage, Mind StoneOpen the Mana Sink pageLegends MatterCards that care about legendary cards: rewards for casting them, discounts, or bonuses for each one you control.Open the Legends Matter pageFree CastCan be cast without paying its mana cost when a condition is met, often "if you control your commander". Because it costs nothing, you can still answer something after your mana is already spent. Fierce Guardianship, Deflecting SwatOpen the Free Cast page
