Creatures adjacent to a card bearing this sigil gain 1 Power.
Leader is a sigil that increases the Power of cards to the left and right of the card bearing this sigil by one. This is true even if the adjacent card is inanimate or does not usually attack, such as a Boulder or Gold Nugget.
Strategies[]
For its full potential, this card should be placed between two cards.
This sigil can benefit from sigils like Dam Builder, Bellist, or anything that spawns other cards like Bees Within or Rabbit Hole. Cards that summon adjacent cards will effectively produce 3 attackers for the price of one, and free cards generated in your hand by sigils will inherit this effect, allowing you to buff a card twice and increase their power by two.
It is also noteworthy that cards bearing this sigil also can be affected by the buff, hence two cards with Leader placed next to each other will mutually increase each other's power as well as the other spaces.
If you're desperate for a source of damage, making use of a Boulder in a Bottle provides a free 1/5, which can be situationally beneficial and possibly allow you to maximize overkill damage at the end of a round.
