I've tried deflags, but unless you're going rainbow or can stay in-element for perm/creature control, it's best to try to focus on your combo. another owl's eye would help. I don't really get the sundial. Do you still heal with it? It only stalls for 1 turn, so it's really only useful to give you 1 more turn to start healing, and you very very often won't draw it early enough for it to be useful. Upgrade the rustlers if you want to start upgrading, since 3 hp lets them survive a fire shield, spine carapace, etc. and gives you a much better winning percentage.
I recommend you replace the sundial and a wind pillar with fog shields. You'll draw one early on fairly often, and it's really helpful to stall until you can get up a hope. You don't awnt as many or more than your hopes, since you'd rather have a hope, but a fog shield lets you play some empathetic bonds and still have a couple turns left to get
to play a hope.
I personally don't really like FFQ rush decks, since they're fairly boring to play and are frustrating against fast rushes/denial/mass creature control decks. However, when they get set up they're dang hard to stop without the right cards.
Good luck!
