Maybe a decent immortal throne deck?

play hella control and use toolbox to find specific immortal throne triggers

find trade encampment to find immortal throne more guaranteed, because we have 5 uniques artifacts, we should be able to draw one pretty early and can focus on seering for Trade encampement

or flood everything and use annual fair to push island leviathan

use seer to find necessary sites etc need to test

also because we are seer we can place thin ices in annoying spots

worst case scenario our throne gets taken out we can use return to nature/kelp cavern or lady of the lake

if we are playing against another water deck lean more towards standard minion control, if not immortal throne
