I think this card could get a small or middle high buff, because it got more indirect nerfs in the last updates than buffs.
v.1.21, same update as last nerf from 6
to 7
-Phoenix (high popularity of fire decks, RoF (byebye Fireflys, Golem (competing growth card,) and this not, because Phoenix only looks nice but also because Fire decks are very effective with Phoenix + Immo)
-Fractal (competing growth card)
-Thorn Carapace (byebye Firefly)
-Flooding (byebye Firefly)
+ Hope
1.24
- Pandemonium (byebye Firefly)
- Steam Engine ( competing growth card, which also got buffed much), it´s faster than FFQ.
+ Wings
1.26
+ Sky Blitz
1.27
- Mitosis (competing growth mechanism)
- Tower Shield (less damage)
- Acceleration (lobo queen , but risky, competing growth mechanism)
- Iridium Warden (queen)
-Arctic Squid buff
+ Sanctuary
+ Dragonfly buff
I think FFQ, got some competing cards, so it could get a buff and some new cards don´t really help, because you can´t use them all in a deck. If you choose more Sanctuaries, then you choose less Hopes (for example).
And in PvP, you see these new "growth mechanisms" more often than FFQ.
Edit:
1.28: nothing
1.29:
+ SoP (more damage)
+/- SoR unupped. ;
- SoR on time creatures
- SoV, SoSac are for stall decks, SoSer for versatile rainbows (too fast)
- Flooding buff
