Ok, but this was not what I asked, I knew they were balanced in their own archetype. Balder can summon a lot of monsters, yes, but that's dependant on your opponent's plus, and this effect only works on the opponent's turn. he brings himself back help aesthetically, and also to trigger Alviss, the new Alfar Konami made. You also gotta remember, that synchro summoning on the opponent's turn is only useful if that monster can disrupt, and the only who can is Freyja who can activate Gugnir from the deck, which isn't too useful.
They also have Handtrap weakness due to only mind consistency (ex. SS Ratatoskr, eff. discard. Ash Blossom Negate. Scoop from there). It's also fair to say they can scoop if you're not careful. Gullveig is a good example, by investing and getting disrupted being almost game for you.
My question was, to rephrase myself, "What can they do, out of archetype". Also, I'm not trying them balanced for the RL game. This me, trying to make so truly good support that elevates the deck to a fairly high tier, not have it be "good". I think there's a stigma around making support to make things good. I don't personally like "1 card fix all our problems" which is why I didn't go that route. This is my attempt at making Nordics not only playable but relevant. But I want one answer from my question, and I'll use the five grade scale right here
Consistency : 3/5
Power : 4/5
Protection : 4/5
Recovery : 4/5
Versatility : ?/?
I am deeply sorry for the confusion, but I have no interest in submitting support no one will consider, if I wanted this to be borderline on playable, I'd have kept it in the card creation channels. But, if I could get an actual BT in, that'd be nice.
Final Remarks: I want it to balanced, but I also want it to be playable in the reckless meta of KoishiPro. And I've already made it clear how I think of the support, consistent, but not consistent enough. Powerful, but not enough removal to give it a 5/5. Protection is good, but not towers level. And Recovery is also good, but they can still be taken down fairly easily. I don't about versatility, because KoishiPro is such wildcard that you never know until it's in, or reviewed by BT.
