Honestly neither are good choices. Bringing dinosaurs back would be an ecological disaster. Bringing historical figures back would be pointless, as they'd be completely unadjusted to modern times. Also you run the risk of bringing back bad people like Vlad the Impaler, Hitler, and Stallin.
I mean 99 trillion is such an exponentially high number it would be impossible to even imagine that much of anything. That dwarfs the Earth's population by a massive margin. And since you've given them faster-than-light speeds, it would basically be impossible for anybody apart from maybe like really high tier characters to defeat them.
I'm not familiar with Simurgh, but Hulk, Godzilla, and 682 should be enough to take out everyone on the other team. I feel as though the Smarts team would have a better chance with some knowledge of the other team and some prep.
