Havoc

Jorbs

One of Ironclad's trickiest cards, both to evaluate and to use correctly. In the simplest situation, you might play a Headbutt to put a strong card you'd like to play on top of your deck, and then play a Havoc+ for 0 in order to play that card for "free". Havoc is often much more complicated than that, though. A 0-cost (when upgraded) way to cause an exhaust trigger which draws cards with Dark Embrace can end up in situations where Havoc+ exhausts a card, playing it for free, and then draws itself afterwards via Dark Embrace, letting you do that again in situations where you have few cards left in your deck. It's also tricky to work out whether or not its worth playing it for 1 energy when unupgraded, while you have other cards in your hand which are more sure things. A very rewarding card to spend some time thinking about and try to squeeze maximum value out of.

This card is a lot more desirable if you can upgrade it. Combo with Headbutt to play a particular card, or just use it to remove cards from the draw pile. Doesn't add much value to the starting deck, making a bad floor 1 pick.
