Yep, I've played it at 2 for a long while until I realized it was basically the only traptrix I was happy to see two-of in my opening hand and I bumped it up to 3 after that.
I view Vesiculo slightly similarly in that I used to run it at 1 when I started because I just wanted to play more traptrix cards and then I cut it because it didn't read as good enough and then when I added it back in to experiment it did something every single time I drew it. It's a deceptively useful card.
