make the health 0, its possible to buff BL's so this could be buffed too. as to the actual card...it definitely needs a nerf.

for a reusable sundial that costs only

is way OP. in a trio, you could make that even more OP by adding a

quint. the extra ability is very useful too, you could have multiple copies of these to stall for 6 turns...that's a lot!
so I'd recommend getting rid of the extra ability of the upgraded version, then waay nerfing the costs. How about 6

to play and 6

to use the skill? I have no idea really if that's still OP or enough to make it UP. the extra costs would make it a lot harder to focus on a separate version of doing damage, such as fire bolts, or use this in a rainbow
although if you get this quinted, you will almost never die (antimattered creatures dont die to fire shield, correct?). so then i think even if the cost is jacked up, its way to useful in a deckout deck to be considered.
