He is a very good hero in decks that require a couple of rounds to set up. I use him in an ent deck and it works beautifully especially with Quickbeam. I use his ability to deal with enemies when I don't have the ent-power in the first few rounds to deal with those enemies. After that, his ability is rarely needed.
Hero. Threat: 12. 2 4 1 5
Cannot have restricted attachments.
Action: Deal 2 damage to Quickbeam to ready him. (Limit once per phase.)
