Toothy, Imaginary Friend

If you draw multiple cards, Toothy's middle ability triggers that many times. If your team also controls Pir, each of those resolving triggered abilities puts two +1/+1 counters on Toothy.

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.

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.

"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."

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.

If enough -1/-1 counters are put on Toothy at the same time to make its toughness 0 or less, the number of +1/+1 counters on it before it got any -1/-1 counters will be used to determine how many cards you draw. For example, if there are two +1/+1 counters on Toothy and it gets three -1/-1 counters, you'll draw two cards.

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.

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

An effect that checks whether you control your commander is satisfied if you control one or both of your two commanders.
