Modern Budget Floowandereeze

Newer, budget friendly version of Floowandereeze, utilizing more hand traps compared to traditional floo decks as traditional floo have very little to no defense when going second in my opnion. If you want to spend a bit more you can easily swap out the Change of Heart to Triple Tactics Talent and also possibly change out the Pot of Extravagance to Pot of Prosperity which is getting a reprint in November. If both pots are too expensive you can also just replace it with 3x Jack in the Hand but I don't recommend it as everyone know how the floo engine works and will just pick out your robina every single time. The deck itself I have tested rigoursly and if that isn't enough proof that this deck is good, one of the best floo players Jacob Banudelos reached top 8 at Lubbock with pretty much the same deck, with only difference being the talent and prosperity swap 

For extra deck it really doesn't matter what you put in, alot of competitive players will put in Zeus and XYZ winged beasts and etc. but I personally just put in random extra deck monsters as sacrifice for my pot cards aha, in this case i just put in traptrix monsters cuz they be cheap and easy to find. 

For general side-decking every round you can swap out the dimension shifter, ash and imperm for other "defensive" cards such as droll (if opponent is draw heavy), cyclone (if opponent is trap heavy), feather storm (if opponent is monster effect heavy), nibiru (if opponent is playing pendulum, alot of summons ...) I generally always just stick to the 3 ash and 3 imperm no matter if I win or lose the first round, but I do switch out the dimension shifter based on what the opponent was playing in the first round + if I won the first round or not. Alot of the times you might not even want to change it as 3 Ash 3 Imperm and 3 Dimension Shifter is just so good as a whole.
