Professor Onyx Snapshot
Oracle Text
Magecraft — Whenever you cast or copy an instant or sorcery spell, each opponent loses 2 life and you gain 2 life.
+1: You lose 1 life. Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard.
−3: Each opponent sacrifices a creature with the greatest power among creatures that player controls.
−8: Each opponent may discard a card. If they don't, they lose 3 life. Repeat this process six more times.

How to Use This Price Page
Each detail page combines current pricing, recent movement, tournament usage, public deck activity, and rules context for one Magic: The Gathering card or sealed product. Use it when you want a single place to evaluate whether an item looks strong, weak, overextended, early, or simply active in multiple parts of the market.
The selected printing or product matters because the same card or release can appear in multiple tracked versions. Changing the filter lets you compare the version you care about, while the surrounding sections help explain whether the move is being supported by competitive play, broader deck-building interest, or recent pricing momentum.
Related views: set explorer, cards to watch, tournament decks, public deck trends, price spikes, and price drops.
