Nykthos Ramp wants to resolve mana dorks and value creatures like Elvish Mystic, Llanowar Elves, and Cavalier of Thorns to power out Storm the Festival, and Doorkeeper Thrull turns off those enter-the-battlefield triggers while blocking their small early dorks. Abrade is a useful way to kill a mana elf or hit an artifact if they bring in Unlicensed Hearse. Voldaren Epicure and one Fiery Temper are the weakest cards here since their creatures are generally bigger-bodied (Old-Growth Troll, Cavalier of Thorns) and single damage spells don't efficiently answer their threats once ramped. Your plan is to race before they hit critical mass of mana and big creatures, so prioritize cheap interaction and pressure over marginal removal that doesn't scale.
