Yes, Sky Sentinel boosts flying units ranged attacks by granting an additional B-dice. It really makes the G-1 a powerful unit, especially when paired up with a leader. SS is a bit boring to play, in that he needs to stay back to be most effective. In that regard, you will find Laser Knight a lot more aggressive. He has to do more of the "heavy lifting" himself, but he can really bring the pain in his Ultra form. That Chain Attack can be just brutal.

Yeah I just misspoke when I said brawl. I had plenty of G1's and Choppers in my force. You can check out the list I used here

Tried to hang back with him, but Pteradax came to me and stomped a lot of my units first so it was difficult to use them against him as I kept having to respawn.

Sounds a lot more like my style. I enjoy monsters like Terra Khan, Gakura, King Kondo and even Rakadon. There's a good chance Laser Knight will be my 'go to' monster for GUARD (although I like Defender-X too).

Althoug his name rarely comes up, I think the Alpha/Mega combo of Armodox is one of the best for Terrasaurs. The Alpha generates some fast dice with Super Stomp + an Insurance Building. Secure a Radar Array and the Mega is brutal with a 7 range high stat blast attack with Beat Back. He also sports a tough 7 DEF.

For PE I would have to say Xaxor. The boost of Charge! And the move ment ability of Jump helps the units of tremendously.

Zorog ain't bad either.
