Herald of eternal dawn + perennation

I'm trying to make a standard deck purely to enable casting perennation on the Herald of Eternal dawn and just waiting for my opponent to concede or run out of cards, but I haven't figured out the best way to do that. Should I use rampy type cards to get the mana early to cast perennation, or should I run stax-type cards like [[Authority of the Consuls]], [[High Noon]], [[Grand Abolisher]]? And then if I'm able to cast it, I also need a way to avoid cards like [[Sunfall]]. I know it's jank I just think it would be fun haha
