Cool mechanics, but Butter is the one card that pretty much just breaks this character completely. You've combined Double Tap/Burst/Amplify to work with any card, gave a it 0 cost upgrade, and then allowed it to stack for potentially many plays through the Ingredient keyword, or you just use it on other Ingredients to get even more than 2x value out of them. Butter->Butter and now your entire turn is double played.

Needed to really think about what to even do with the card, short of removing it entirely, maybe it would be alright if Butter could only double play Ingredients. That's still an incredibly strong interaction, maybe still too strong, but it's a fun enough interaction that I'd like to see what happens if you let it have that while taking away everything else.

It's true Butter is power creep on the other doubled cards since it's an ingredient, but the upgrade costing 0 isn't since the other cards have a different kind of upgrade. I agree that it being only used for ingredients could be a good solution for balance, but I think it makes it a less exciting and more annoying card to draft than usual (since ingredients can be tricky to spec into). Exhaust and ethereal could work but some ingredient generation already has this so it might make butter generated via those means still a little too strong. Upping the cost could be a quick fix (2 -> 1) but I'll mull it over a little more :)

As for the double butter situation, two of the same rare is very unusual to draft so I don't mind if this is stronger than usual. Sometimes playing butter second (after another ingredient) instead of first and second is actually a better play, since you can only play so many cards anyway, and I like that strategic play.

Thanks! Keep the comments coming

I'll be publishing a huge balance pass to the game later today - made and tested the changes, I just need to document the changes before publishing. Keep the feedback coming, I really appreciate it!

General overview is that Chip sources will be nerfed, starter cards are both nerfed, butter cost nerfed, and some numbers tweaked. Full list of changes to come!

So... Mixing bowl is bugged right now: every time past the first time played, it will increase how many cards you draw by 4.

In other words: upon playing 2 Mixing Bowls, you'd draw 5 cards for every 4 cards played.
Safe to say, this is absolutely broken when coupled with the way ingredients upgrade to cost 0.

Also, this isn't a one-time thing; playing 3 Mixing Bowls increased my card draw to 9. Yeah.

Ah damn, I changed the variable logic for Mixing Bowl and must have messed it up somehow - rest assured it should only trigger 1 draw every 4 cards (multiple mixing bowls increases the draw amount). I'll get this fixed tonight. Thanks Makel!
