Spike Bomb

==Notes==
* Fallen Venom leaps into the air, then lands near a hero, threatening to explode next turn.
* Exploding counts as an action; if Fallen Venom manages to explode, he will only have 1 action next turn instead of 2.
* Spike Bomb's Area of Effect is represented by a red, broken circle.
* Spike Bomb seems to prevent Join Us from triggering.
