can use any fetchlands (that fetch a forest) it's to trigger Groundswell's landfall trigger to pump your infect creature

giver of runes is to get your infect creature protection (could consider Apostle 's Blessing - loses colorless but gains artifacts)

noble hierarch is to ramp

drayard arbor is to ramp, can be fetched, and triggers groundswell

pump spells: 
Become Immense (need to delve)
Blossoming Defense (gives hexproof)
Groundswell (has landfall trigger)
Might of Old Krosa
Mutagenic Growth (can pump for 2 life - great to play multiple in a turn for lethal)
Vine of Vastwood (pump and protection)
Distortion Strike (small pump and unblockable)
Scale Up (big pump - but at sorcery speed)

Land
Botanical Sanctum - UG fast land (tapped unless 2 or fewer)
Breeding Pool - UG shock land
Hallowed Fountain - WU shock land
Temple Garden - WG - shock land
Waterlogged Grove - UG pain land
Misty Rainforst - UG fetch (not used?)
Flooded Strand - WU fetch
Windswept Heath - WG fetch
Wooded Foothills - RG fetch
Inkmoth Nexus - 1/1 flying infect
Pendelhaven - 1/1 creature pump -can you pump the 1/1 then use other pumps?

A turn two kill can result from: t1 any land + Glistener Elf, t2 any of the following, all starting with a second land drop:
*Groundswell + Scale Up
*Might of Old Krosa + Scale Up
*Blossoming Defense + Scale Up + Mutagenic Growth
*Mutagenic Growth + Mutagenic Growth + Scale Up
*Might of Old Krosa + Groundswell + Mutagenic Growth
...and almost any combination of three Mutagenic Growths + anything else you can think of will do the trick

On top of this heinous amount of ways to kill turn 2, we also have a fairly solid capacity to turn 3 our opponents with protection for our creature. This can be accomplished a number of ways, but most often it is with a t1 Noble Hierarch, t2 Infect creature + protection up in the form of Vines of Vastwood, Blossoming Defense, Spell Pierce, or Apostle’s Blessing and then the requisite amount of pump t3 often with the same protection available.
