Built Bear’s legacy ability can increase its mana cost depending on how many points you spend. If you spend 0 or 1 points, its mana cost remains . If you spend 2 or 3 points, its mana cost becomes . If you spend 4 or 5 points, its mana cost becomes . And so on.

Playtest cards use a modified version of game symbols, such as and . These modified symbols should be treated as the standard symbols during play.

Calculate Built Bear’s mana cost after you’ve finished circling options. That mana cost is considered to be printed on the card and is part of its copiable characteristics.

All of the circled abilities are considered to be printed on the card. They are also part of Built Bear’s copiable characteristics.

During deckbuilding, you may circle any number of options in Built Bear’s text box, such as flash, ward , +1/+1, and “When this creature enters the battlefield, draw a card.” Each option is delineated with a line break or semicolon, and each option can only be circled once. The options you circled must be clear and understandable to all players.

Playtest cards aren’t legal for play in any tournament format other than Mystery Booster Limited formats. On the other hand, we expect they will spice up a wide variety of non-tournament games (as long as everyone’s on the same page about using them!).

For many playtest cards, you’ll need to make a generous assumption that basic game rules would be updated to allow them to work. The Mystery Booster 2 Playtest Card Notes section (reproduced here in individual Gatherer rulings) provides guidance for fitting these cards into the existing rules structure.

If you circled any of the power/toughness changes (+1/+1 or +0/+2), they are applied to Built Bear’s printed power and toughness and are also part of Built Bear’s copiable characteristics. For example, if you circle +1/+1, Built Bear’s printed power/toughness is 3/3. But if you circle both +1/+1 and +0/+2, its printed power/toughness is 3/5.

If your deck and/or sideboard include multiple copies of Built Bear, you can circle different options for each Built Bear as long as the choices for each one are clear and understandable to all players. Each individual Built Bear can have a different mana cost and different printed characteristics depending on what was circled for it.

During a game, ignore any printed parts of Built Bear’s rules text that isn’t circled except for the legacy ability. For example, a Built Bear that doesn’t have any options circled is a 2/2 with no abilities except for legacy (which has no in-game effect because nothing is circled for it).

In a Limited format with Continuous Construction, you can modify your circled options for Built Bear in between matches, but you can’t modify those options during a match (such as while sideboarding in between games).
