Icaria Nostrix

"Icaria Blue" meets "Hooru Midrange"
Turn 5 - Jotun Feast-Caller/Throne Warden
Turn 6 - Nostrix, Lord of Visions
Turn 7 - Icaria, the Liberator
Turn 8 - Win!

Deck Choices:
Icaria, the Liberator: This has always been one of the best finishers in the game. At 4 I found it a bit of a brick, might try 3. I didn't want to splash too much Fire in.
Nostrix, Lord of Visions: This covers Icaria, the Liberator's weaknesses, bigger flying creatures, plus a surprise +5/+5 is awesome.
Jotun Feast-Caller: Throne Warden's are a good budget alternative, also depends if you want more recovery or a win-more card.
Rise to the Challenge: In most "Icaria Blue" its a 1 of at most, but because Nostrix, Lord of Visions buffs all the creatures in the deck, you can draw 10/7 Jennev Merchant's.
Polymorph: I think this is a very underrated card. There's no spot removal like Annihilate or Slay for FJP decks, and a 1/1 Frog is nothing to worry about, also stops Inquisitor Makto and other sticky creatures.
Jennev Merchant: Access to Hailstorm, Polymorph, Thunderstrike Dragon and Channel the Tempest. Aegis is a very big bonus too.

Market:
You can put whatever you want here. I went for Thunderstrike Dragon as you can swap the echo back in later and create even more.
