When I was first testing Floowandereze, I forgot Gren Maju Da Eiza even existed. Yet here I am, making a Gren Maju deck after I got OTK'ed by one a few days ago. So, the point of this deck is to banish as much cards as you can befor summoning Gren Maju on the second turn or controling your opponent by Floowandereze. However, be VERY careful that you don't deck out yourself by banishing too much. Also, Pot of Desires is very dangerous to play because it banishes almost a quarter of the deck and can kill many of your important cards or combo pieces. The Extra deck is only there to be a tool for Pot of Extravagance, so just fill it with the cheapest cards you can find. Overall, fun, but very situational rouge deck. So good luck!
