Pioneer version of my modern deck https://aetherhub.com/Deck/Public/29056 This was my first modern deck and won many LGS events and did well on mtgo. I also day 2'd my first SCG Open with this in Louisville in 2018. The only non-land downgrade from my current list is to .

1CMC Creatures:

  1/1 Flyer with sacrifice to counter instant / sorcery unless opponent pays 1. Very useful and slows down opponent with having the ability to tax spells.

  Judge's Familiar but gets bigger when you play a spirit and can tax more when it has higher power. 

Flash spirit that can pump familiar or draw cards late game

2CMC Creatures:

  pumps wanderer and can also sacrifice to give the rest of the team indestructible. Very useful

hasty 2/2

3CMC Creatures:

3/3 Flying, Vigilance, Haste American Eagle. Do not underestimate the vigilance part of this card.

2/3 Flash Spirit. Can counter "can't be countered" spells since it exiles them. Also can give surprise lethal by flashing in on opponent's end step or pumping wanderer on your turn.

Noncreatures:

  the best noncreature in this deck. Can be used offensively or defensively

  pumps the whole team. "haste" damage

can be sent at face or to opponent's creatures / planeswalkers

Sideboard:

  the best aggro/tempo counterspell in my opinion. Could go with if wanting a more ability. is also a strong option

  a one sided instant pyroclasm that is killer against aggro decks. I used to play in the modern version to much success even though it hurts my team.

  awesome graveyard hate

  nonland interaction and a flashy flyer

  oblivion ring but can convoke creatures. Most useful after attacking with creatures and a Rally of Wings. Other options include and . I had much success with Cast Out in modern

Other Builds:

UW Sephara Spirits https://aetherhub.com/Deck/Public/176848 Mostly cutting red and going harder in spirit synergy and . Could also cut Sephara and add green for like modern bant spirits or make it a more tempo UW spirits build. Slightly more budget friendly

  this card is amazing in standard UW flyers and can be good here. If playing 4 Foresight's, I would cut 2 lands. Recommended other cuts for foresight are Shock or Favorable Winds. You can go down 2 Shocks for a full playset of 2 Favorable Winds.
