So... You need to already have some field advantage to summon it, have 2200 ATK while Psychic Borg can go to 2500 on first turn and gain up to 1000 each next turn it is a "beatstick" that hurts you by destroying monster and without help from any other cards, the best you can summon with it's effect is a psychic monster with 1050 atk... Yeah, this is definitely a UR card, something i want to farm the entire event for to get 3 prismatic copies and make an entire deck centered around.
I mean, I am not saying it is a completely useless card, i actually use 1 Kicker in my psychic deck, the thing is: there is a lot of other psychic type monsters that would make better UR drops for Roba, like Master Gig or Psychic Snail or hell, even Mind Protector. In my opinion Armored Axon Kicker should be SR or something.
He's basically an alternative for Overdrive Teleporter. You could E-Tele Krebons, then summon this and synchro into Stardust Dragon. However these 3 aren't in play (yet). In my opinion, he is only worth running as a beater right now. unfortunately, Borg does the job better. A SR would fit him better indeed.
Actually, i think Kicker is going to be more useful when they release Ra, to maintain the field full of tributes, only problem is you will lose precious LP that could have been spent to make Ra stronger.
