Commune with Lava is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
Exile the top X cards of your library. Until the end of your next turn, you may play those cards.
Complete guide
Commune with Lava is a powerful red ritual that allows you to dig deep into your library for answers. By exiling the top X cards, you gain access to a temporary hand that lasts until the conclusion of your subsequent turn. It is a premier example of red's impulsive draw mechanic, rewarding players who plan their mana usage carefully.
What It Does
When you cast Commune with Lava, you choose a value for X and pay that much mana plus two red. Upon resolution, you exile that many cards from the top of your library face up. Unlike some effects that only last for the current turn, Commune with Lava allows you to play these cards until the very end of your next turn.
How It Resolves Step by Step
First, the spell checks the value of X as it resolves and moves that many cards to the exile zone. Second, a continuous effect is created that grants you permission to play those specific cards. Third, you must follow all normal timing rules and costs for the exiled cards; for instance, you can only play a land if it is your main phase and you have a land play available.
Common Mistakes
A frequent error is forgetting that 'playing' a card includes both casting spells and playing lands. However, you still cannot play a land on an opponent's turn. Additionally, any cards left in exile once your next turn ends will stay there for the rest of the game; they do not go to the graveyard or back to your library.
When to Play It
The most effective time to cast Commune with Lava is during your opponent's end step. By doing this, you untap all your lands on your turn and have the maximum amount of mana available to cast the spells you just exiled. It effectively turns your mana from a previous turn into card advantage for your current one.
Interaction examples
If you exile Deflecting Swat with Commune with Lava, you can cast it from exile. If you control your commander, you can even cast it for its alternative cost of zero mana. This allows you to protect your permanents from targeted spells using the cards you've stashed in exile.
Imagine you cast Commune with Lava for X=4 on an opponent's turn and find Chaos Warp. Because Chaos Warp is an instant, you can cast it immediately from exile as long as you have the mana. This provides a flexible way to remove a threat that wasn't even in your hand moments ago.
