Corpse Explosion

It might seem obvious to some but Corpse Explosion stacks, so when you apply it more than once, that creature will do its max HP x2, x3, x4, etc., to the amount you throw down cards.

Relic Synergy

• The Specimen relic is very powerful when used with Corpse Explosion, since it transfers any poison to another creature when it dies.  That means anything that didn't die from the explosion inherits the stacked poison.
• Snecko Skull provides a bonus +1 poison to any poison effect, making Corpse Explosion that much stronger.
• Twisted Funnel applies 4 Poison to all enemies at the start of combat.  Combined with Corpse Explosion, it gives you a head start on killing the off.
• Gremlin Horn provides a bonus Energy and 1 card draw.

Strategies

• When fighting multiple opponents, especially those with minions, inflict Corpse Explosion on the minions.  When they die, they inflict their max HP on the minion leader.  If you have The Specimen, then they inherit the stacked poison as well.  If its an elite or Boss that summons multiple minions, you can repeat this on the minions, who are usually weaker and easier to kill, while transferring heavy damage to the Boss or minion leader.
