For aggro decks with a low curve, yeah. But for mid-range decks with a bunch of Painters, Zendos, EMPs and Hamons, your hand will get clunky real quick. Suppose mid-range can still survive if it plays a more aggro game I guess.
I could be wrong though, since I am but a peasant compared to your songhai greatness.
@gsvalhalla, when I said jaguar was gonna affect meme decks, I specifically meant decks built around movement that also include cards like black locus. You can definitely swap out Hamon or Geomancer for Jaguar though when playing a regular mid-range deck.
