UG saproling mill
This deck revolves around the mill and landfall mechanic and abusing life and limb to get additional land drops through saprolings.
Starting with creatures:
Your two crabs are your win con. As you get your land drops you should be milling your opponents as much as possible.
Lotus cobra will help you ramp into your combos and other cards faster through it’s landfall and if your lands enter tapped you can still get mana from your cobra. This is even better if you manage to get multiple on the field at the same time.
Your sporemound will help you put saprolings onto the field as you put more land cards onto the field. This will combo with your life and limb to put infinite saprolings, which will also be lands and trigger your landfall abilities. If you have at least one crab on the field you will infinitely mill every opponent and win.
Tireless tracker essentially has landfall for clue tokens which sacrifice to draw cards
Non-creatures:
Maddening cacophony is a flexible mill card that can drain libraries very fast
Kodama’s reach helps you land ramp and puts an additional land into your hand so that you will be guaranteed 2 land drops that turn.
Explore draws you a card while allowing you to play an additional land which will trigger your landfall cards. If you have at least one lotus cobra on the field this will have a mana neutral effect while giving you card advantage and triggering your other landfall effects
Life and limb turns your saprolings into forest lands and your forests into saprolings. This will help you get even more land drops and ramp you very fast while triggering you landfall abilities for every saproling that enters the field.
Saproling migration puts either 2 or 4 saprolings onto the field. If a spore mound is in play this will put either 2 or 4 forests into play and trigger every landfall ability either 2 or 4 times. That’s potentially +4 mana for every cobra, milling 4 cards for every crab, etc
Lands:
Simic growth chamber can tap for 2 mana and bounces a land back to your hand which would allow you to get another land drop and landfall trigger from it.
Blighted woodland allows you to get a land drop of if it and can either tap for colorless mana or be sacrificed to search for 2 basic lands which would each get landfall triggers of their own
Side board:
Jace Memory Adept helps deal with opposing decks that either have effects that shuffle their graveyard into their decks, such as the eldrazi Titans, or get some benefit from enter the grave yard effects that would interfere with you winning from outright milling. By forcing your opponents to draw you still exhaust their deck but prevent their graveyard from shuffling back into their library.
Preordain helps you consistently pull whatever you need by scrying 2 then letting you draw.
No escape is another option to deal with eldrazi type creatures that would shuffle graveyards into libraries while also drawing you a card.
Tempt with discovery is a very good land ramp card in this deck especially if you are playing with multiple opponents. Potentially you could get 4 land drops from it in a pod of 4 people and get 4 separate landfall triggers. If you have a lotus cobra or 2 then you would also get 12 mana to use from those 4 land drops. You can also grab any land since it did not specify basic which could be used to grab your dual lands or blighted woodlands. Your lands also come in untapped so if you grabbed woodlands you could immediately sacrifice them to get more land drops and more landfall triggers.
If you guys have any suggestions to improve the deck let me know. Thanks for reading :)
