i actually decided to make 2 decks. 1 "weaker" with adjustments but overall keeping my cards as they were ,which is the link at the start and another, not yet fully finished, deck with your adjustments
https://www.duelingbook.com/deck?id=12256059the cards i adjusted were:
Balb, Guard of the thieves guild
Can attack your opponent directly. If this card attacks, switch it to defense position at the end of the Battle Phase. If this card inflicts battle damage: You can look at your opponent's Deck and place 1 card from it on top of it.
At this point..can i ask you how you color the text in your posts? i have rly no idea how i could do that ^^
To the card: i liked your idea of simplyfing the eff so i implemented it without changing the whole card
Graila, Tactician of the thieves guild
Can attack your opponent directly. If this card inflicts battle damage, you can special summon 1 "Thieves Guild" monster with level 3 from your deck.
I thought thats a small but significant powerup cause you can immediatly attack with the new monster.
Pia, Sharpshooter of the thieves guild
This card can attack your opponent directly. If this card attacks your opponent dircetly, you can change its ATK to 0 during Damage Step only and if you do activate 1 of these effects:
● Banish 1 card from your opponents hand
● Banish 1 card from your opponents side of the field
I just made her more versatile so she isnt "useless" if the opponent got no cards in his/her hand
Thieves Guild Hideout
All "Thieves Guild" monsters gain 300 ATK and DEF. Up to 3 times per turn, if a "Thieves Guild" monster inflicts battle damage, you can activate 1 of the following effects:
● Your opponent discards 1 card
● You can send 1 card from your opponent´s side of the field to the GY
● You can banish the 2 top cards of your opponent´s deck
Cause of testing results i changed the "your opponent chooses one of these effects" so that you can choose which effect you want to activate because if not the opponent would always banish the top 2 cards
Varas, Leader of the thieves guild
You can normal summon this card without tribute if you have at least 4 "Thieves Guild" monster with different names on the field or in the GY. You can special summon this card from your GY if you control 4 cards including at least 2 "Thieves Guild" monsters with different names. This card can only attack monsters in defense position. As long as this card is on the field, your opponent cant target other "Thieves Guild" monsters for attacks also other "Thieves Guild" monster are unaffected by card effects.
I added your ss from gy effect and increased his shielding potential with giving him also the "other "Thieves Guild" monsters are unaffected by card effects" bonus without preventing the opponent from activating them at all. Also, due to his high stats and easy summoning conditions, i didnt want him to become an attacker so he kept the "only attack def pos" trait.
I think that were all changes so far.
As much as i can understand the changes you suggested but other duelists wouldnt agree with such a powerfull deck in customs which is sad but understandable (also sadly^^). Thats the reason why i made 2 Decks. 1 powerfull and 1 that i actually can play with without the opponent quitting after reading the first card effect(and insulting me before they leave. its customs after all
)
