Understand this is all small sample sizes...

It costs 1575 to fuse a common card. At level 19 it costs 1365 per card and at level 20 it costs 1845 per card to boost.

Using a hypothetical card, here's how it breaks down...

A card gives 20 xp and costs 1365 to use it to boost at level 19. It gives the same xp but costs 1845 at level 20. So that's what you're invested, 1365 and 1845 respectively. C

That card fused would give 40 xp, just a simple double. I haven't done extensive testing, so that may be incorrect, but it did the couple times I did it. So at level 19 it would cost you 2940 to use a fused card (1365 to use it to boost, and 1575 to fuse it), where using the two base cards would only cost 2730. Each example would net 40xp. At level 20 it would cost 3690 to use two commons(1845 to use to boost times 2), and only 3420 to use a fused(1845 to use to boost and 1575 to fuse).

Uncommon appears to start being more efficient to use fused at level 30, but I haven't paid attention when I had a card that was level 30 to confirm prices.
