This can really help when you have no cards that you can play and need to reset your hand
Top loaders serve as rigid protection for high-value cards during storage or shipping
Belakor doesnt help you ramp to your demons, but it does give you a massive wincon in the command zone, and being a Grixis commander gives you access to blue, which means you can use some of the cheaper, powerful blue-touching demons from 40k like Exalted Flamer of Tzeentch
It works well because I run several cost reducers like Ugin, the Ineffable, so I can put them into play with Flood of Tears ability and replay most of my board immediately
Which, if you have been following my review
