Reinforce

Reinforce is an activated keyword ability that functions only while the card with reinforce is in a player's hand. It was introduced in Morningtide. By 2010, it was considered a design failure. The mechanic is a modal mechanic that adds an overcosted combat trick mode, which despite the potential choices tends to be far too clear-cut as to when each side is relevant. The space of modal combat tricks was revisited in Bloodrush, which had a stronger feel but nonetheless still had a lukewarm reception.
