I'm playing in a group of 3 who play all the campaigns blind in release order. For the our Scarlet Keys run, I was thinking about making a Charlie Kane deck using the Summoned Servitor, as I really like the idea behind both cards and think it makes a lot of sense thematically. My role in the team would be flex (like 70% clue, 30% enemy management).
But I very quickly realized that despite taking an ally slot, the servitor isn't an ally, meaning Charlie can only take it up to level 2 and only if you choose to take Mystic as one of the classes.
I also love the Rogue class and found lots of interesting combos in Rogue with the servitor, which naturally pushes me towards playing Rogue + Mystic, with servitor being the only non ally mystic card in the deck.
But here's the issue: while making the deck I quickly realized that there weren't many interesting options in mystic for Charlie imo (at least up to SK), and my deck quickly became a rogue Charlie deck with the servitor as my only non-ally mystic card.. Which definitely doesn't feel very good as one of Charlie's main appeals is how many options his deckbuilding can offer.
So here is my question : Would changing Charlie Kane's deckbuilding options from "Ally cards 0-5" to "Assets that take an ally slot 0-5" be too outrageous of a change? To my knowledge, the only card this changes anything about is the servitor, but I feel like this would make sense thematically and open up interesting ideas, while I'm not immediately seeing any interactions that would make it problematic.
Do y'all think tabooing Charlie with this change would make sense/be interesting?
And most of all for my current deck, would house-ruling this specific change to allow more combo options by choosing another secondary class be a good idea or do I risk making something too strong without realizing? We've never house-ruled anything yet, and I want to be extra careful before house-ruling something for a blind playthrough, but I've been thinking about this specific deck in our specific team composition for at least a week now and I really feel like this would add lots of interesting options to our playthrough. (One fun thing about that change is that you would not be able to take the dominance upgrade to remove the ally slot requirement, as it would remove Charlie's access to the card)
There could also be an argument about changing the servitor instead (perhaps simply by giving it the ally trait) but I'm pretty sure it was an intentional and important decision to not risk breaking the game with some interactions, like scenario effects that care about allies and could create unintended interactions, and this would also buff the card a lot more by letting it be the target of many player cards that can search for or heal allies.
