This is a pretty self explanitory floowandereeze deck. You want to start the duel with shifter, dd crow, or one of the pots. If opponent go with bagooska pass then you need to make Codebreaker Virus Link monster to beat over bagooska. Once bagooska is off the board you can normal summon Empen if you have a normal summon left. Empen isn't like the other Floow monsters in the sense that they can't activate their effects if you special summoned. Empen on the other hand can still search and give an extra normal summon without clashing with special summons.
Some potential issues you can run into are activating macro cosmos before using DD Crow. Crow is mainly used going second during opponent's turn 1 plays. Once the grave is lockdown, Crow becomes fodder for Unexplored Winds to draw cards.
The side deck is full of good alternatives to swap incase you find yourself bricking. Also Vanity's fiend pairs well with shadow imprisoning mirror because the mirror stops activations of effects and our fiend doesn't need to activate to floodgate. If you have Vanity Ruler from Legacy packs then it is a better alternative since it only stops opponent from special summons.
I am always a fan of people playing Snowl, but I understand if people would rather have an extra Empen or run Apex Avian. Just remember to try and limit your self to 4 tribute summon targets to avoid bricks. Shifter is an exception since it doubles as a hand trap.
