Buddy

Buddies are special monster cards used during gameplay. At the start of the game, each player chooses 1 monster from their deck and places it in their buddy zone. During a player's main phase, that player can call their buddy from the buddy zone. This is known as a buddy call. When a player buddy calls, they gain 1 Life. Buddies do not count towards the 50-card minimum deck size, nor do they count towards the "4-per-deck" rule.

Buddies carry significant strategic value because they improve a deck's consistency by making an important monster easily available. This is particularly useful if you want to build your deck around a specific monster's effect.
