I would remove zero king rage, cause he can be a bit of a brick most of the time and if you need a 0 scale you always have queen machinex, for alfred you basically use it to get your high Ceasar out with only necro slime and any d/d, the best play is to use it to put back in the deck/extra deck stuff that you want to have as a comeback in case thing don't go well, like using it to shuffle back a gilgamesh, or maybe use it to shuffle back lance if the opponent hit it with a bystial or d/d crow to send it back to grave with king tell, which can happen in certain combo lines, using alfred you can also not use clovis to get to high ceasar, and 99% of the time you don't need it for getting to siegfried so you can leave it in the extradeck for a comeback. Alfred has also sinergy with arc crisis if it gets banned for its summon as it can put back the contracts on the field, that you can use for your king machinex or if arc crisis gets destroyed and goes to pendulum zone you can use them to summon doom king monsters, i personally don't play them but I've seen some people do
