First, I would love to have that option; and second, I think this will be a nice addition for the plugin, not only for me; but maybe other users as well. It will give us more control when harnessing the chaos/randomness of the game.
For example, in the case I use, If we have an early card that produces a random "Fire" card BUT we do not want to give the player something has powerful has, for example, "Nuke", we can filter the pool of cards to give to the player, while still maintain other types of interactions like the one you have with the plugin Independent Card Variables,
In which you show a card effect to increase the damage to certain types of cards. Arcane charge is the name you give to that card.
A plugin I might get down the road, but right now, I need to make sure my project Idea works with what I have, and my potential testers give me at least a "Good enough" review; before going deeper into getting more plugins, which includes the Independent Card Variables, which is a Patreon plugin.
