So I really like the build and the way it's set up. However, I found that this deck might have a problem with big flyers. Is there any solution to that (besides burn, which won't really take down very big creatures)?

I would run Dig Through Time over Treasure Cruise. Technically a bit harder to cast, but double blue shouldn't be a big issue, and I think the two best of the top seven is better than three randoms off the top. Also it's instant speed so you can hold up a Shrapnel Blast and if you have no reason to use it, then you can Dig.

FAMOUSWATERMELON: Truthfully, I hadn't really considered how to deal with large flyers, so thank you for bringing that up. Singing Bell Strike has been useful against difficult-to-manage threats. Shrapnel Blast isn't pretty as removal but it works in a pinch against Master of the Feast, and I don't think I'll really be able to deal with something like Prognostic Sphinx or Pearl Lake Ancient. Maybe Force Away in the sideboard?

tl:dr anything big and scary i either lose card advantage to kill or try to ignore it and focus down opponent.

evncrbch: Good suggestion on Dig Through Time. I have 1 so i'll probably run one alongside a single Treasure Cruise until I get a second. Thank you!

Singing Bell Strike would probably be more effective. Maybe add one or two to the main deck? Even forgetting flying, it's a good form of defense.

FAMOUSWATERMELON yeah, gonna try two Singing Bell Strike mainboard instead of Ghostfire Blade, also removed 1 Island in favor of a fourth Swiftwater Cliffs--fixing has been an issue for this deck and so Cliffs T1 seems like a better play than Ghostfire Blade, which has really only been a tip-off for what I'm playing and a flag for removal.

I made an artifact list awhile back. It's on my profile if you want to go visit it. Maybe you'll like what you see and get some ideas.

Auto +1 for Strong Bad

Alright, two things:

First, I love this deck so much I'm making my own modern version of it, but taking a couple of your ideas.

Second, Ugin's Nexus needs to find a way in here. You play it, sacrifice it with Shrapnel Blast and you deal 5 damage and get an extra turn for 2 mana.
