This is a version to remove any seartching/revealing/shuffling/time wasting. Its a little more powerful but much more streamlined

Unless you're using a loaded die, this probably isn't very good? You've got a 50% chance of only getting a 1/1, and in exchange you get a 2.5% chance of getting three. (and a faction of a percentage chance of getting more - with an unlimited upside).

So while "It might be worse than a bear, but it might be really good once in a million" is a card I might run, I'm not sure why you'd want to run a deck filled with loads of these. (Is it being basic a holdover from the previous one that went searching for a copy?)

... I kind of want to suggest the old search version in preference - since I went looking to find out what the heck a 'dretch' is and my first hit was a green dragon. So if this was upposed to have a chance of fetching that it would be kind of interesting.

What if the 1-10 was not "Do nothing." but "You may put a card named Dretch from your hand onto the battlefield."?

Not only would it mean the "a deck can have any number"-clause matters again, but it would also help with the scaling, you might prefer that result before 11-19 if you have the card.

Though the card disadvantage is still a thing hurting that option.

In DND Lore, a Dretch is the weakest type of Demon, it can gate in others of its kind like most demons but this only has a 50/50 chance of success, whilst very occasionally leading to a small horde of the buggers. This is what I was trying to capture with the card. Also, with cards that let you roll more dice and choose the result this gets much better.
