This version of Drytron has performed very well for me, the inclusion of Linkbelt Wall Dragon has proven very useful, I can SS him right after summoning linkuriboh, he can be used as a material for Beatrice (lvl 6) or just leave him on the field as a floodgate for link decks (opponent can't summon link monsters with link rating higher than its counters and can't attack your herald of ultimateness with non-link monsters)
Also, Number F0: Utopic Draco future can be easily summoned with Drytron gamma after reviving Mu Beta Fafnir from GY.
