While there may be more efficient or versatile options available in certain deck archetypes, Lone Rider can be a strong inclusion for decks looking to capitalize on lifegain synergies and aggressive strategies
Without the opponents cooperation, you have to do the work yourself with Ingest creatures, which seems like a pretty low power-level and worth avoiding in Constructed
In the sideboard, I also like having a split on the two-mana removal spells because I think Declaration in Stone is better overall, but Fateful Absence is better against Abzan Greasefang
Shoot, that card still makes my Top Five
