Notes:

• A slight synergy has been starting to take shape of untapping/giving vigilance to mana dorks to enable them to attack and produce mana. This is fun to see, but need to see if I can protect them sufficiently so they aren't at risk of dying in combat. If I can get this to stick, it would add a nice unique spin and feel to the deck
• Skullport Merchant: maybe okay, but sustained card draw is preferable. This deck generally does not want to sacrifice creatures and pay to do it
• Abzan Charm: okay for flexibility, but this deck would rather not spend mana for no tempo card draw. Since this is in a land slot, replacing with mana ramp
• Gods' Hall Guardian: unimpressive. Takes up the mid-mana slot even after discount for a somewhat larger body, but no other benefit. The discount isn't enough to take it down one tier in terms of mana curve (4 mana for just 6 toughness and nothing else often still doesn't trump playing other 4 mana-ish cards), and I still have to pay the foretell so it's not really even a discount
• Spectral Gateguards: testing out to see if it helps with enabling mana dorks to attack and thus have more tempo
• Loam Larva: very unimpressive. basically a tiny card when I have sufficient mana, which should be the case more often than not
