Updated Roon (EDH / Commander)

Revisions:
Nature's Lore to Cultivate- few one drops to play on turn 2 off untapped forest, ramping to 4 matters less than ramping to 5
Tempest Caller to Sunblast Angel- Tempest Caller is best used with instant flicker, not end of turn.
Serum Visions to Acidic Slime- need more explosive plays, serum visions is the worst of the cantrips

New Revisions, months later:
Sunblast to Loaming Shaman- Need some graveyard hate, worth dropping a hard to control boardwipe.
Acidic Slime to Serum Visions- cantrips are king.
Watcher for Tomorrow to Brainstorm- I play all the fetches I own in this deck, in addition to all the basic land ramp, enables BS to be awesome. Watcher has always underperformed.

Revival Revisions:
Rewind to Counterspell - Rewind is too cute, would prefer the efficiency of counterspell.
Bant Charm to Teleportation Circle - Bant charm is inefficient and narrow at what it does, would prefer more non-commander flicker options.
Sun Titan to Marsh Flats - I want the mana to be more perfect, and Sun Titan synergies are mostly for ramping with fetchlands.
Brutalizer Exarch to Venser, the Sojourner - Exarch is either a slow tutor or inefficient interaction. I want to use Venser to lean more into small creature tb's and to be another win con if the combo goes bust.
Fierce Empath to Guardian Project - With Sun Titan gone and the transition to more of a control deck, we can use the draw more that the ability to find Deadeye Navigator.
Serum Visions to Spellseeker - The worst cantrip to a really great toolbox card. The lowering of the curve helps allow serum vision to be replaced.
Duplicant to Swords to Plowshares - With Fierce Empath gone and the addition of spellseeker, we want to be able to have more targets for spellseeker and to interact with creatures earlier. We do miss the mass creature control, but spellseeker finds cyclonic rift and this, so we aren't dead in the water without him.

The Birthing Pod Line:
This takes two turns. Get Saffi Eriksdotter into play either through saccing a 1 drop or some other tutor. Sac her to birthing pod to get Renegade Rallier, getting Saffi back. Next turn sacrifice Renegade Rallier to get Felidar Guardian, etb flicker birthing pod. Sacrifice Saffi targetting Felidar Guardian, then sacrifice guardian to pod to get karmic guide. Etb reanimate Saffi, etb flicker birthing pod. Now sacrifice Saffi targetting Felidar Guardian, then sacrifice Felidar Guardian to get Peregrine Drake. Etb untap 5 lands, etb flicker pod. Now sacrifice Karmic Guide to get Deadeye Navigator, soul bond to Peregrine Drake, get infinite mana. You can now sacrifice the last Felidar guardian to get Thragtusk and get infinite life and beast tokens and win next turn.
