If you're still having trouble with Circus Trick, just fill your deck with Tenkabito Shien (you can get it via Card Trader), E-Hero Wildheart, Trap Jammer, and Straight Flush. Fill the rest of your deck with normal monsters with 1500+ ATK and DEF (to bypass Curse of Anubis and to ensure they wouldn't be beaten in combat while in defense) and spell/traps that can destroy traps and hopefully set cards, and you should be good, even with Auto-Duel. Yes, compared to other decks of this stage, Circus Trick is *far* ahead. Still, just push ahead, and once you reached Stage 33, you won't have to worry about this deck ever again. Making a separate deck might be annoying... but this is the stuff you will be doing to farm Lv40 Legendary Duelists anyway.
The Reverse Trap deck can be really annoying too if you can't deal with it fast enough. Reverse Trap in particular, if you can't counter or lock it down, you'll ends up hitting into a 4000 ATK Flash Assailant.
Honestly it makes ZERO sense that we need to change deck just for Circus Trick....that's the very definition of a broken deck, that we need to use very specific counters just to counter that one deck. If that happens, it means that one deck is broken and should not be allowed.
Dunno why Konami still hasn't change it....not enough people complaining?
Use a ritual deck yourself.
The strength of rituals is that they can quite fast summon strong monsters and you mostly can do nothing about it. The answer is summoning or buffing something over 2000 fast or decreasing your opponet's attack enough also fast.
I countered circus trick with the trap 'rebound' when a trap'spell or effect that returns a card from the field to the hand, send 1 card from opponents field or hand to gtaveyard. Plus if that set card is destroyed, draw 1 card. I Always win with 'rebound'against circus trick
