This is a modified version of the traditional
Hooru Fliers. I took out
Shelterwing Rider because
Vara is too widespread at the moment and despite the fact that Shelterwing combos so unbelievably well with Nostrix and Unseen Commando, I felt that those combos are currently too cute given the dominant decks (HH pings the rider for free and then combusts to remove her out of the sky). I also cut Hooru Pacifier because Vara essentially requires you to run Vanquisher's Blade right now. Weapons are nice when you run Caiphus especially if he rolls Berserk+Double Damage which amounts to 28 damage in one attack if he wears the blade.
However I suspect the optimal Caiphus shells are shadow-based for Dark Return, which is substantially better than Mirror Image. It is also likely that Caiphus wants to be partnered with Jenny, so she can fetch Mirror Image once he is actually on the board. The ability to go Jennev -> Mirror Image at 6 power the turn after you have played Caiphus is extremely strong.
There is probably an argument for a
Hailstorm variant of this deck, but I feel it wipes too much of your own board and too many decks currently run units that don't care about
Hailstorm (ex.
Vara, Vengeance-Seeker,
Statuary Maiden,
Zuberi, Outlands Warlord,
Rizahn, Greatbow Master,
Knight-Chancellor Siraf or
Caiphus, Wandering King) or the decks themselves don't really care about the impact of the spell (ex. Haunted Highway, Talir Combo, Westwind Combo).
Svetya, Orene of Kosul is a very strong pick at the moment and drawing her alongside
Mirror Image can win games right now.
This deck may be stronger in a future meta.
Making Jenny into an 8/7 then cloning the empowered Jennev with a maindeck mirror only to fetch another mirror, will lead to a board with 3x8/7 Jennies and 1x5/7 Nostrix prior to removal. If they don't have a Vara and a sweeper that will often be enough to seal a game.
The idea for the abundant amount of power is to hit 8 and 9 power respectively. Svetya can bring you back into a game on her own by activating her ability for 8 power and 9 power allows you to play Caiphus and clone him on the very same turn before the opponent can use their removal. Towards the mid and endgame you also want the power to hold up Unseal fairly reliably.
In regards to Hooru Aggro, I would recommend these two variations on the archetype:
Spells Don't Matterâ„¢
No Rule's Sky
I think Hooru Aggro probably has to run Pacifier because of how important such a strong 3 drop is in that setup, coupled with berserk and/or Commando it can easily become your MVP and biggest threat on the board. This means you have to sacrifice Vanq Blade and rely on Commando sticking while having spare blockers in the air.
