Hi everyone, this is my first published deck so feel free to comment and tell me what you think about it.

I'm currently playing on mythic ladder, mainly Bo1 for testing it and I will make it optimal for Bo3 after enough matches. So i'm not sure about the sideboard right now.

This is really fun and cool to play tho, you can juke your opponent with Justiciar's Portal and trigger again card effect like Frilled Mystic, Knight of Autumn or Dream Eater.

Most of cards are played in flash so you can anticipate opponent move and apply some "mind pressure" during his turn. 

Don't forget that Justiciar's Portal add first strike on creatures so it can be really usefull for blocking opponent's creatures.

                                                           - MAINBOARD -

- For early game Seal away and Knight of Autumn can help you to deal with aggro decks. (The Knight is really versatile and can also deal with enchant, you can trigger different ability with only one if you bounce it)

- Cleansing Nova and Settle the Wreckage to clean up board

- Mass manipulation works well to deal with planeswalker or big creatures in late game.

- Some cards draws and ramp with Growth Spiral, Chemister's insight and Azcanta.

- Frilled Mystic is your main counterspell and can apply pressure since it's a creature (really love that card)

- Krasis is pretty strong for everything (I found 2 copy enough, but I don't know if more is really efficient, that's why I add one more copy in sideboard)

- Dream Eater is pretty good, make you able to surveil 4 and bounce an opponent's permanent, also strong enough to deal with many creatures

- Wilderness Reclamation isn't used like in nexus deck to have a huge manabase but it fit pretty well in this deck, you're allowed to full tap with a Teifeiri or a big Krasis and still ready to flash cards in opponent turn.

- Teifeiri as win condition on it's own, nothing much to say about him ;)

                                                         - SIDEBOARD -

- Dawn of hope, Entrancing melody, 2 extra Seal Away  good for facing strong aggro early.

- Deputy of Detention, can be used to deal with midrange decks, and also can be triggered with Justiciar's Portal

- Angel Of Grace, help you in a lot of way, also flashed (it can be an alternate win condition, I didn't found the place to put them in mainboard so idk.)

- Ixalan's Binding, to deal with anything boring.

- Disdainfull stroke and extra copy of Syncopate and Negate for control or nexus matchup.
