Forum:Need help with TGU agent

Hi, after I tried my TG agents, it didn't work well. So I switched to TGU agents. I need help for something:

1.Is TGU our Pure agents better?

2.Is it better to get tgu and 2 birdman than 1 birdman?

3.is gellenduo good in pure deck?

Thanks for answering. P.S. I played proxies, so no TGU price discussion please.
