Alright so the main changes from the tcg one:
1. Branded is still your worst nightmare, but now with it running more rampant than in the tcg, you have to be careful when you send stuff.
2. Dogma for chuckles when you summon albaz.
3. Chimera and fiendsmith millenium make the deck way better than generaiders, but generaiders still aren't bad. The side deck just contains more options. If running kash package, run more Hecahands Godos (I would go 2 at max) then you can cut the generaider stuff, and run millenium and a small fiendsmith package.
If you really want to run generaiders, then just know you might brick a bit. **This is the smallest possible generaider package**
Between vampire guy and pilgrim reaper I have no idea what is better.
I do know however, that if you run reaper, then you should probably be running Nightmare Apprentice, as you want to be milling your generaider fairy.
Other things to consider: black goat, cutting some of the heca spells/ traps replacing non engines to what you'd like etc.
Please ask any questions!
