Mono-White Landfall: Oswald Fiddlebender (EDH / Commander)

Mono-White Landfall
This deck breaks the mold of Mono-White by doing a Green thing in Landfall. This deck does not do any of the typical White archetypes.

How this deck wins
Generating value from Landfall triggers that buff your creatures, create tokens, and tap down enemy creatures.

Combo
There are no infinite combos, but there is one single-turn combo that will dump ALL of your remaining Plains from your Library onto the battlefield.

Combo Setup
-Ashnod's Altar on the battlefield (or your choice of repeatable sac outlet)
-Emeria Shepherd on the battlefield
-Amulet of Vigor (optional)
-Solemn Simulacrum (SS) or Kor Cartographer (KC) in hand

Combo Execution
-Cast SS or KC
-Sacrifice creature to Ashnod's Altar in response to its own ETB trigger. This will put the creature into the graveyard BEFORE the resultant Landfall trigger occurs. If using SS, draw card in response to its death trigger.
-Return creature to battlefield via Emeria Shepherd's Landfall trigger
-Rinse and repeat until all Plains are put onto battlefield

Combo Result
-An enormous number of Landfall triggers
-A fistful of cards in hand if using SS
-Twice as much floating colorless mana as Landfall triggers, due to Ashnod's Altar
-All tutored Plains are untapped due to Amulet of Vigor

This combo produces one VERY explosive turn because of all the Landfall triggers, but also because of the fistful of cards in hand that can be cast with the floating mana and fresh Plains. This combo can make for some VERY memorable games.

Strengths
-High card synergy, focus, and recursion capability.
-It's SUPER unique and innovative.

Weaknesses
-This deck is highly dependent upon getting Helm of the Host onto the battlefield and keeping it there.
-High dollar cost.
-Lots of moving parts, can be difficult to catch up or rebuild.
