I'm surprised that Fate Eggs are that much more popular than Devonian Dragons.
Also, as much as it is known that Silurian Dragons are often worse than Devonians, I'm surprised that Dune Scorpions are upgraded much more often than dragons ???
Deja Vu are also a bit surprising. Generally speaking, there is so much difference in power between upped and unupped, I wouldn't be surprised if upped was used more often than unupped. But, it's the opposite. I wonder why. In unupped mono I would sooner use a Fate Egg than a Deja Vu, since 2 damage for 2
that is blocked by most shields isn't great. In upped mono, Deja Vu are a mediocre addition to build up some early damage. In duo and rainbow, Deja Vu can be used for: buffing, immolation, fractal, bonds. Fractal Deja Vu and Deja Vu + Bonds are too weak unupped, and also suffer from the shields too much. Immo Deja Vu is only seen in PvP events that require 50% Time, since you'd rather take photons/sparks if you can. That leaves buffed Deja Vu the only reasonably good unupped Deja Vu deck. And I haven't seen these that often, especially since buffed Dune Scorpions arrived.
Everything else seems to make sense. I would think Pendulums could be used a bit more often when compared to Factories, since most good Time decks are duos, but it's understandable that mono decks and beginner decks are used often enough by newbies to cause such results.
