When casting a card this way, ignore timing restrictions based on the card’s type. Other timing restrictions, such as “Cast [this spell] only during combat,” must be followed.

If you cast a card “without paying its mana cost,” you can’t pay alternative costs such as overload costs. You can pay additional costs such as kicker costs. If the card has mandatory additional costs, you must pay those.

If the card has in its mana cost, you must choose 0 as its value.

If Æther Searcher leaves the battlefield before its ability resolves, you’ll still be able to search for the named card and cast it.

If the card you draft after Æther Searcher is a land card, you won’t be able to play that land using Æther Searcher’s ability.

If Æther Searcher is the last card you draft in any draft round other than the last one, you’ll reveal the first card you draft in the following draft round and note its name.

If Æther Searcher is the last card you draft, there won’t be a noted name. You can still search your hand and/or library when it enters the battlefield, but you won’t cast any card this way unless you also drafted an Æther Searcher and noted a card then.

If an Æther Searcher owned by another player enters the battlefield under your control, you can search for a card you’ve named while drafting a card named Æther Searcher, not a card named by its owner. Unless you also drafted a card named Æther Searcher, you won’t cast a card.

You cast the card before shuffling your library (if it was searched). In some very rare cases, you may need to take actions involving your library while casting the card. For example, if it has an additional cost and you activate Deranged Assistant’s ability (“, Put the top card of your library into your graveyard: Add to your mana pool.”) to pay for it, you must maintain the order of your library while you search it.
