Ya, it's hard to tell if leveling up fusers is useful. I haven't really looked into it that much. I think for a general rule it is probably best not to level up the sacrifice card. My reasoning is that in the past it was useful because rare cards were more valuable and you wanted to get the most growth for the cost. However, now rare cards are cheaper (~30k) and the minimum growth is higher for cards with better rarity. If you are to try and increase the level of the fuser then for low levels you will be losing those cards, and spending more to fuse the fusers, and then more for fusing the "enhanced" fusers. At higher levels or higher rarity base card you would have to overcome a large "growth penalty" in order to actually increase from the minimum growth. I just don't see it being useful to purposely level fusers.
