Unexpected ConversionHow it works & interactions with other cards

What It Does

When you cast Unexpected Conversion, you first draw two cards. After drawing, you have the option to exile one instant or sorcery card currently in your hand. If you choose to do so, you search both your hand and your library for any number of additional cards with the exact same name as the exiled card and exile those as well. Finally, for every card that was exiled specifically from your hand during this process, you Seek an instant or sorcery card.

How It Resolves Step by Step

First, you draw two cards. Second, you decide whether to exile an instant or sorcery from your hand; if you don't, the spell finishes. Third, if you did exile a card, you look through your hand and library for any number of matching cards to exile, then shuffle your library. Fourth, the game checks how many cards were removed from your hand (the initial card plus any duplicates found there) and you Seek that many random instant or sorcery cards from your library, putting them directly into your hand.

Common Mistakes

One common mistake is forgetting that you only Seek for cards exiled from your hand, not your library. If you exile one copy from your hand and three from your library, you only Seek once. Additionally, because Seeking is a keyword action that grabs a random card of the specified type from your library, you do not get to choose which instant or sorcery you receive, nor do you shuffle after Seeking.

When to Play It

This card is best used when you have 'dead' spells in hand that aren't useful in your current matchup. It allows you to transform those useless cards into random, potentially more relevant spells while ensuring you never draw those specific redundant copies again for the rest of the game.

Interaction examples

Converting Extra Tutors

Fabricate

You cast Unexpected Conversion and draw two cards. You have two copies of Fabricate in your hand but no more artifacts to find. You exile one Fabricate from your hand, then search your library and hand for others. You find the second Fabricate in your hand and exile it too. Because two cards were exiled from your hand, you Seek two random instant or sorcery cards from your library.

Thinning the Library

Windfall

You have one Windfall in hand and three left in your library. You cast Unexpected Conversion, draw two, and exile the Windfall from your hand. You then search your library and exile the remaining three copies of Windfall. Since only one copy was exiled from your hand, you Seek exactly one instant or sorcery card, but you have successfully removed all Windfalls from your deck to improve your future draws.
