Custom Card Ideas: Soul of the Pure
Hate Curses, Traps, Madnesses, and Disasters? Who doesn't? Wishing Rings are rare, and other cards are few and far between. You'll get Curse cards at times to play on others, but they're nonsensical and ineffectual. Lose 1 Small Item? Okay, here's my Rat on a Stick.
Why not just ignore the (mostly) whole aspect of the game altogether?
What Does the Card Do?
Here's Soul of the Pure which makes you "Immune to Curses, Traps, etc. but you are unable to play any as well."
Someone plays a Curse against you? They wasted their card. Kick down the Door to reveal a Trap? It goes immediately into the discard pile. Think of it as a less powerful version of the Magnificent Hat (it doesn't reflect Curses or give you a bonus to your combat level), but a more powerful version of a Wishing Ring (in the fact that it's permanent).
However, this card also means you can't play any other people, or yourself. Any Curse cards you draw when you Loot the Room will be practically useless. Is it a worthy trade off?
One last thing that is important to note is this card is like a Wishing Ring. A Voodoo Zombie from Munchkin Zombies cannot draw a Treasure after playing a Curse against Soul of the Pure, since it's canceled out before being taking any kind of effect (unless you still want to afford a Voodoo Zombie a Treasure based on house rules).
You're Curse-proof, but you can't use the Curse cards you obtain. However, you can trade them off to other players. This is good for a variety of reasons. You have nothing to fear for giving away a card that does you no good. It won't come back to bite you. Also, you stand a decent chance in getting something better, even if it's just a one-shot item. Furthermore, one indirect consequence of playing a Curse card is earning the ire of another player. When you encourage another player to attack another, you are more likely to remain insignificant and a less satisfying target to your rivals.
That also means, my other custom card, Hex Direx Gloves, is limited in what you can do. If you own both the Soul of the Pure and the Hex Direx Gloves and someone plays a Curse against you, you can't use the gloves to move it onto someone else. However, if someone else plays a Curse on someone other than you, you can use the gloves to move the Curse onto someone else (unless you decide to change it for your house rules).
Keep in mind, if it's not a Curse or same card by a different name (Trap, Disaster, Madness, etc), this card will NOT stop it. That goes for things like Rocks Fall Everyone Dies, Malign Intervention, or some of my custom cards like Genocide, Chinese Fire Drill, Ritual Sacrifice, and so forth.
