I just bought him instead of Atum's BG (maybe a mistake, but I LOVE his design)...anyone hatched him yet? Is Holter's BG any good as a support?

According to the Wiki, he's best suited to be a healer as opposed to a warrior.

Excellent stats, first of all. Tankier than Keithor, with speed comparable to Scrap Warrior. Not much of an attacker tho, hes a supporter with superb healing. Too bad he doesnt have Tough tho

I love his design as well.

honestly, I think it's garbage.
