Warcry

This card is intended to be used to make your current turn and the next turn have better options. It synergises well with Havoc, since you can control which card is played and exhausted. You might think that this card has no possible downsides since it is free and draws, but enemies like the Chosen, the Time-Eater and the Heart make Warcry a less valuable pick. For this reason, I would not generally recommend picking one except perhaps early. As a side-note, warcry can be used in combination with Fire Breathing to draw and re-shuffle curses and statuses into your deck.
