This is what I think will happen, not that I agree with it.
Karakuri: the current limit 2 will be swapped to merchant, the shs card they use also at 2. Konami doesn't give a damn about f2p decks, sorry shs users.
Dragunity and Lunalight will get another card to 2, to prevent dragunity from using trunade and because Lunalight is cheap and can steal wins.
Bamboo Scrap to 1
Level Aug will d i e
No UR will be hit this time, it is bad for the business.
No relevant xyz deck until December or January.
I think Level Aug, Dup & Red will have LP loss requirement after this.
Assuming Level skill will be changed to have LP loss requirement, Blackwing might get Simoon or Whirlwind to limit 3, to prevent play with Cosmic Cyclone
I suspect Shira will get another 1 or 2 cards to limit 2
Drag might get 1 other card on semi and 1 card on limit 3
The scrap recycler looks likely, it is a free card after all.
with destiny draw I'd say your opponent takes no damage this turn and you can only special summon once. with balance you can't conduct your next draw phase.
Endless trap hell is not a problem now but it definitely should leave, it is a +1 for doing absolutely nothing. Maybe forcing you run only traps and trap monsters.
lol all the skills are kinda cheating. zane summons 2-3 materials for an otk, auto adds non destruction removal, 1/4 of the skills start the game +1 with a field spell.
I dont believe they should nerf skills. I believe they should update some older skills to be useable. Level augmentation is only being used in shiranuis. Balance is what makes playable some decks like aromage, triamids, dm etc that are not even tiered atm. Destiny draw should be used when you have less than 2000 lp.
Balance is the skill need to be nerfed. A skill that can prevent bricking in a 20 cards format should not be allowed. Imagine if TCG allow you to play like this then everyone would do it.
