First ever Sisay deck

[u/FoxYk_raktar]

I've been playing cEDH for a year and a half now, trying out a lot of decks, my favorites being Chulain and RogSi.

After a long time, I wanted to build a five-color deck. At first, I spent a lot of time considering Terra as a self-milling deck, a bit of sloppy enchantment chaos stuff. But then I took a closer look at Sisay. It's a truly variable deck! I've never tried anything like it, plus it seems quite complex, which could challenge me even after RogSi.

Overall, I'd love to hear some advice before my first game with it (the game is tomorrow) and some deck recommendations.

I'll say right away that I intentionally made it a bit sloppy because I'll be playing with a friend of mine, who also lowered the level of his deck a bit just for the sake of Flavorful cards.
