Official rulings

The 8 most recent official rulings for Haldan, Avid Arcanist, newest first.

• 2020-04-17 "Partner with [name]" represents two abilities. The first is a triggered ability: "When this permanent enters the battlefield, target player may search their library for a card named [name], reveal it, put it into their hand, then shuffle their library."
• 2020-04-17 A creature card that you exiled with a fetch counter on it may be cast as a noncreature spell if a rule or effect (such as that of adventurer cards) allows you to do so.
• 2020-04-17 A creature with a "partner with" ability can't partner with any creature other than its designated partner. Losing a partner ability during the game doesn't cause either to cease to be your commander.
• 2020-04-17 Both commanders start in the command zone, and the remaining 98 cards of your deck are shuffled to become your library.
• 2020-04-17 Haldan doesn't change when you can play the exiled cards. For example, if you exile a sorcery card, you can cast it only during your main phase when the stack is empty. If you exile a land card, you can play it only during your main phase and only if you have an available land play remaining.
• 2020-04-17 Haldan's ability applies only while it's on the battlefield. You'll be able to play cards you exiled with fetch counters before Haldan entered the battlefield, and if Haldan leaves, you won't be able to play cards that were exiled with fetch counters until Haldan returns.
• 2020-04-17 If your Commander deck has two commanders, you can only include cards whose own color identities are also found in your commanders' combined color identities. If Haldan and Pako are your commanders, your deck may contain cards with blue, red, and/or green in their color identity, but not cards with white or black.
• 2020-04-17 In a multiplayer game, if a player leaves the game, all cards that player owns leave as well. If you leave the game, any spells or permanents you control that Pako fetched are exiled.
