Banners seem like a really cool idea, they're like the opposite of traps too where you'd want to put them out of the way so they don't get landed on. I wish they added more than 3 of the them though, it could be a long time until our next card pack
That new gift card that lets you place traps anywhere within a radius of you is absolutely insane holy hell

I'm not really crazy about these two cards though. Go with the Flow just seems like a much worse here and there. It really should be free. Meanwhile Full Burst has that same Price of Power effect that I feel like no one ever uses. Most cards aren't higher than like level 3 and you won't really be able to play a higher level card early on because they're usually expensive
