For a general strategy, check the usual lists of Geoffrey and others. Will add one some time in the future. If you have any ideas or suggestions, feel free to write me in the comments.

Here are the main differences of my list considering Mirage is nerfed now and the new courts are out which in my opinion makes it way more dangerous to play early unique minions and uniques in general:

3x Pebbled Paths: While they can theoretically harm your Border Militia/Onslaught plan, I found them just too good against Mono Fire Pathfinder and other fire decks with a lot of charge minions, in many cases even better than Gnome Hollows. Just place them in your back row or away from your opponents sites when you play a control mirror and want to run your combo.

3x Funeral Pyre: A choice for the increasing amount of Archimago mirrors. Played 3 of them at Sorceryfest and they can really make a difference in a mirrormatch.

Cut of early unique minions:

The Earth and Fire courts will dramatically impact your ability to safely play your early Unique cards or be able to play them at all. Therefore my intention is to reduce the amount of Uniques I play to a reasonable minimum. While creatures like Michael and the Deathdealer have way too much impact not to play them and cheap cards like Tithe and Pendragon Legacy are also strong and not completely dead if they cost more, I decided to cut semi optional cards like the Saint of Redemption, Mover of Mountains and Goat of Azazel for now. Especially the Saint doesn't seem that necessary if we play 3 Pebbled Paths in the deck anyways. Sister Stefania is too good to be cut for now.

Full Set of Firebolts:

While they make the Algor Omphalos slightly worse, I really like the idea of playing more Firebolts. They are a cheap spell filling your graveyard and allow you to get rid of multiple early threats more consistently, whether it is a Sinterfee, Skeleton Tokens and tokens in general or an early Imposter mask you want to get rid of. If you want to play the Smite (I am testing without right now since it was mostly underwhelming with cc4), just play 3 Firebolts or 3 Border Militia instead of 4.
