stick with wingal brave as the starter.
-If you choose fullbal, you are compelled to add 4 blaster javelin which is totally irrelevant when u hit grade 2. u are wasting 4 precious slots on a pathetic 6k boost where u have access to marrons and toypongals
-extending my point from playing 4 marrons and toypongals, i believe u understand the idea of the so called magic number. your MLB ideally wld touch 12k, with a marron/toypongal boost gives you 20k/21k respectively. that is paramount for sufficient pressure for your opponent to drop 20k guard on your vanguard attack every turn.
-triggers are good btw and so far, take out the blaster javelins ensure that u have 4 marrons and 4 toypongals.
Which brings me to my next point, still focusing on your grade 1s, the additional isolde is a great idea btw as u can really sustain that amount as you're playing 4 draws. And let's presume you still wanna play 14 G1s, so u have..
-2 Friendship Kay(G1 that can push a 10k early game is no joke, it's a nice fill in and a decent 7k boost i strongly recommend this instead of other cards for this slot)
Now your G2s, first thing i have to point out is that your blaster dark, honestly all u need is 2 as it's no way as useful as blaster blade, i presume it's self explanatory as blaster dark is an SP and yes i understand our concern the possibility of bringing that card into your soul, but thats where these cards come in, wingal brave and starcall. which brings to this debate about u adding 2 wingal brave and starcall.
-Point are pretty good cards but u could only choose one of the either.why?
-let's analyse starcall, it's an 8k if i recall and it requires 2 CBs to call out a blaster TO THE FIELD. i caps as it's an crucial point to take away, u don't have the flexibility of putting it into your field, ergo if your field is full, u have to sacrifice a RG for nth. and you wldnt have the choice of blasting an oppenent RG with your blaster blade at the right time. but it is still a G2 with a decent effect and a free intercept.
-Wingal Brave, this lil dude packs a punch with it's effect, not only it's free but you could place the card u pulled out into your hand, however it's a G0.
-So who to choose? Personally i'll definitely go for wingal brave.
Firstly, it's a free effect, the CBs are better used using blaster blade's effect blasting off a RG, and trust me it's a pain in the [censored by admin].
Secondly u could use it to pull out an MLB from your deck. starcall can't do that as u have to call it to the RG circle, why wld u do that for an MLB?
Conclusion, it's really up to your choice which is more ideal to ur play style as u may realise wingal brave effect to pretty hard to pull off at times as your attack has to hit. taking the pros and cons into consideration hopefully u can make a better informed desicion.
Which means your G2s will look like this
-4 blaster blade
-4 bedivere (the loyal that u mentioned i presume)
-2 blaster dark
-2 starcall/wingal brave
-Oh yeah i forgot to mention, but move in pulling out the loyal, u are blessed with 4 marrons and toypongals which allows him, a G2 to hit a menacing 20/21k. dam why wld u give up a power like that? your opponent will go crazy just seeing him.
Finally the G3s, i like your idea of the G3 line up but 1 ssd may seem to be pretty insufficient, if u wanna play it i suggest at least 2. your deck would do very well without it as well, since you're limited to 7 slots only, u may wanna drop one MLB for another SSD or if u don't feel safe with 3 MLBs, drop the SSD and play another palo. in a diagram,
an insight on SSD, an ideal soul will have a random G1,G2,blaster dark and blaster blade,wingal brave. that's already 5 which lays an awesome foundation for SSD, u even have margals for support if it's not enough. further more u realise at 5 dmg your crits becomes obselete and thus and SSD is awesome for a final turn when your opponent has 5 dmg and below 6 cards in his hands.
Your current G3 line up is pretty decent as well actually but i just feel that 1 SSD just ins't enough heh. but if u feel lucky and can draw it every game great! leave it as it is haha
Hope i helped enough. good luck!
