[BRO Sealed] How can I build around Portal to Phyrexia?

https://sealeddeck.tech/41zBA1UwEf

This is for the qualifier play-in and also the first time I've seen Portal in draft or sealed. I'm tempted to try to build around it, but my blue doesn't have a lot in the way of powerstone generation.

Should I just let Portal sit on the sidelines and go BR sac-ggro? Or maybe BR anyway but try for more of a mid-range brew for once?
