Mammon, along with every other attack-oriented gachapon Demon, is a 30-cost powerhouse. Thanks to the way buffs work, his main skill can be a huge boon to your own power. Unfortunately, he's part of the ever-growing Death Scorpion, but it doesn't detract much at all from his overall value. If you see him come up on the weekend, feel free to be greedy and spend all of your stones, he's worth it.
Mammon's skill comes with a neat gimmick, where every target you hit has a chance to have ATK/DEF "stolen" from them (you will inflict -1/-1 and gain +1/+1 in turn), which means you can gain up to +3 ATK/DEF on a single turn with him. The catch is that this only works once on the target, so if you target a specific monster with his ability you wont ever inflict more than -1 or gain more than +1 ATK/DEF.
A 20% skill efficacy boost is significant, but due to the lasting nature of buffs and debuffs, chances are you wont be willing to use it on most things. Though like many cards, he ends up being one of his own better subs, in this case because his main skill can negate the penalty of his subskill.
