This frog commander will draw you approximately a billion cards by dumping lands in the graveyard, whether its by discarding them with Noose Constrictor, sacrificing them to Sylvan Safekeeper, or milling them with The Mending of Dominaria and Wrenn and Seven
Next in line would be Goldspan Dragon, but the truth is that theres nothing that can properly fill its spot
it costs nothing to use, and it can also be used as an interrupt
With a ton of wonderful two lore characters with strong willpower's such as Daisy Duck, Donald's Date and characters that can even bring themselves back into play such as Lilo, Escape Artist, this deck is a fierce contender that can reach 20 lore in only a few turns
Lifeline is a colorless card with such an effect, with the drawback being that it's symmetrical and affects all players creatures not just yours
You can abuse the adventure side to fill your hands with adventures or cast the commander to make cards with adventure cheaper
