Card ID: #215 "Ancient War"
Rapid Putrefaction - 2 Mana Cost, Dark Element, 61 Damage, Decreases this monster's attack by 20.
Enormous Explosion - 1 Mana Cost, Void Element, 65 Damage, This monster falls in battle when the attack is used.
SP Skill - 5 Cost, Inflicts instant death on the opponent's summoned monster of Cost 2 or less.
Reverse - 3 Cost, Increases this monster's ATK by [your Mana x 2].
An interesting card, obviously made to take advantage of its own reverse skill, with very heavy damage attacks that either force you to swap it out after a couple of attacks or sacrifice it. There is almost no situation where you would want to use the Dragon Zombie's SP skill and Enormous Explosion feels out of place seeing as no element is resistant to Dark element damage. Rapid Putrefaction is you real bread-winner here 60+ damage is huge anyway and 2 mana is a steal, you will have to switch Dragon Zombie out after a few swings with Rapid Putrefaction (to reset its values) as it's attack power rapidly dwindles.
Keep in mind also, the Ruin God deals 50+ damage for 4 mana and the card itself costs 10 mana to field.
