Jeskai with blink mechanics control.
This deck is primary built around boros colors(): Ephemerate, Ardent Elementalist and Cleansing Wildfire the rest of the deck to takes advantage from theese cards and support them. Because of this, you can build as Mardu () or Naya () colors.
Play Ephemerate on creatures in order to make them trigger "enters the battlefield" ability. And if you play on Ardent Elementalist it can be repeated all the times you want, also take as much you want Spells from your Graveyard.
Cleansing Wildfire have immense value if played on indistruttible lands, because it cantrip and mana ramp+mana fix. Also, on indistruttible lands mechanic is very valuable the introduction of Kenku Artificer, giving a 3/3 flying indistructible creature on board, and abusing with Ephemerate is verey interesting.
There are many builds of this deck, and in maybe board i placed many interesting cards. And few considerations from maybe list:
Azure Fleet Admiral Aarakocra Sneak takes good advantage from Guardian of the Guildpact in order to take back/mantaining/steal) both monarch and initiative mechanics.
Mirrorshell Crab and Sword Coast Serpent are playable as spells in early game and gives good options in late game as bombs/closure, both takes advantage from Late to Dinner.
Peel from Reality can be played as multiple removal, taking it back from G.Y. if targetting Archaeomancer. Same way Settle Beyond Reality, is pretty interesting, but with sorcery speed is to much to handle.
There are many cards that give to this deck a swiss knife options. Theese cards are: Izzet Charm - Fire / Ice - Hindering Light - Abrade.
