Pir, Imaginative Rascal — ruling 1

If a permanent your team controls would enter the battlefield with one or more counters of any kind on it, it enters with that many plus one instead.

Pir, Imaginative Rascal — ruling 2

If an effect includes multiple instructions to put one or more counters on a permanent, such as Lifecrafter's Gift does, Pir's effect applies to each of those instructions.

Pir, Imaginative Rascal — ruling 3

Pir's effect can't apply to itself as it's entering the battlefield or to any other permanent entering the battlefield at the same time as it.

Pir, Imaginative Rascal — ruling 4

"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."

Pir, Imaginative Rascal — ruling 5

Note that the target player searches their library (which may be affected by effects such as that of Stranglehold) and that the card they find is revealed, even though these words aren't included in the ability's reminder text.

Pir, Imaginative Rascal — ruling 6

The second ability represented by the "partner with [name]" keyword modifies the rules for deck construction in the Commander variant and has no function outside of that variant. If a legendary creature card with "partner with [name]" is designated as your commander, the named legendary creature card can also be designated as your commander. For more information on the Commander variant, please visit Wizards.com/Commander.

Pir, Imaginative Rascal — ruling 7

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 Khorvath and Sylvia are your commanders, your deck may contain cards with red and/or white in their color identity, but not blue, black, or green.

Pir, Imaginative Rascal — ruling 8

Both commanders start in the command zone, and the remaining 98 cards of your deck are shuffled to become your library.

#9June 8, 2018· Wizards of the Coast
To have two commanders, both must have the partner ability (featured in the Magic: The Gathering—Commander™ (2016 Edition) set) or corresponding "partner with" abilities as the game begins. 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.
No other card is named in this ruling.
#10June 8, 2018· Wizards of the Coast
Once the game begins, your two commanders are tracked separately. If you cast one, you won't have to pay an additional the first time you cast the other. A player loses the game after having been dealt 21 damage from one of them, not from both of them combined. Command Beacon's effect puts one into your hand from the command zone, not both.
No other card is named in this ruling.
#11June 8, 2018· Wizards of the Coast
An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
No other card is named in this ruling.
#12June 8, 2018· Wizards of the Coast
The triggered ability of the "partner with" keyword still triggers in a Commander game. If your other commander has somehow ended up in your library, you can find it. You can also target another player who might have that card in their library.
No other card is named in this ruling.
