Classic midrange windfall deck.

Core strategy is to ramp with multiple ramp spells in order to get to your windgrace cast quickly, then you have drawing power and landcasting possibility from your graveyard. You will almost never used windgrace ultimate cause he is a bit hard to scale consistently (your board presence takes a while to set up). Once you have a good number of lands you will snowball, given you have the drawing pot and threats in hand.

Landfall synergy is there (avenger of zendikar, Baloth woodcrasher, Nesting Dragon) but most of your plays are gonna be big bois and devastating but costly sorceries. Win con is to save your board/Cmdr/life until late game then it's trample fest and board wipes each turns. Most of your ressources are gonna be drained in the meanwhile but then you get Graveyard interractions to get your bombs back. You also have a bit of built in protection for your windgrace but most of it a creature based (Thantis, Emissary).

Needs to set up, will struggle against decks that can bypass your creatures to kill Lord Whiskers McPurry, armaggedon (ig haha) and decks that will bounce or counter your big bois (although you will be able to pay fee after the mid game). Fares well vs mill decks (given you still draw some graveyard creature interractions) and group hugs/symetrical decks.

Not much interractions with other decks you just focus on gathering your big bois and collecting lands.
